-Installation Instructions
-*************************
-
-Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004 Free
-Software Foundation, Inc.
-
-This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  (Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.)
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You only need
-`configure.ac' if you want to change it or regenerate `configure' using
-a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-Some systems require unusual options for compilation or linking that the
-`configure' script does not know about.  Run `./configure --help' for
-details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not support the `VPATH'
-variable, you have to compile the package for one architecture at a
-time in the source code directory.  After you have installed the
-package for one architecture, use `make distclean' before reconfiguring
-for another architecture.
-
-Installation Names
-==================
-
-By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PREFIX'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PREFIX', the package will
-use PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-There may be some features `configure' cannot figure out automatically,
-but needs to determine by the type of machine the package will run on.
-Usually, assuming the package is built to be run on the _same_
-architectures, `configure' can figure that out, but if it prints a
-message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the `--target=TYPE' option to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-If you want to set default values for `configure' scripts to share, you
-can create a site shell script called `config.site' that gives default
-values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-will cause the specified gcc to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-`configure' Invocation
-======================
-
-`configure' recognizes the following options to control how it operates.
-
-`--help'
-`-h'
-     Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-Version 3.99.93
+Version 4.2.93 (03 Jan 2020)
+
+A complete list of bugs fixed in this version is available here:
+
+http://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id=108&set=custom
+
+* WARNING: Backward-incompatibility!
+  Number signs (#) appearing inside a macro reference or function invocation
+  no longer introduce comments and should not be escaped with backslashes:
+  thus a call such as:
+    foo := $(shell echo '#')
+  is legal.  Previously the number sign needed to be escaped, for example:
+    foo := $(shell echo '\#')
+  Now this latter will resolve to "\#".  If you want to write makefiles
+  portable to both versions, assign the number sign to a variable:
+    H := \#
+    foo := $(shell echo '$H')
+  This was claimed to be fixed in 3.81, but wasn't, for some reason.
+  To detect this change search for 'nocomment' in the .FEATURES variable.
+
+* WARNING: Backward-incompatibility!
+  Previously appending using '+=' to an empty variable would result in a value
+  starting with a space.  Now the initial space is only added if the variable
+  already contains some value.  Similarly, appending an empty string does not
+  add a trailing space.
+
+* WARNING: Backward-incompatibility!
+  Contrary to the documentation, suffix rules with prerequisites were being
+  treated BOTH as simple targets AND as pattern rules.  Behavior now matches
+  the documentation, and pattern rules are no longer created in this case.
+
+* New feature: Grouped explicit targets
+  Pattern rules have always had the ability to generate multiple targets with
+  a single invocation of the recipe.  It's now possible to declare that an
+  explicit rule generates multiple targets with a single invocation.  To use
+  this, replace the ":" token with "&:" in the rule.  To detect this feature
+  search for 'grouped-target' in the .FEATURES special variable.
+  Implementation contributed by Kaz Kylheku <kaz@kylheku.com>
+
+* New feature: .EXTRA_PREREQS variable
+  Words in this variable are considered prerequisites of targets but they are
+  not added to any of the automatic variable values when expanding the
+  recipe.  This variable can either be global (applies to all targets) or
+  a target-specific variable.  To detect this feature search for 'extra-prereqs'
+  in the .FEATURES special variable.
+
+* Makefiles can now specify the '-j' option in their MAKEFLAGS variable and
+  this will cause make to enable that parallelism mode.
+
+* GNU make will now use posix_spawn() on systems where it is available.
+  If you prefer to use fork/exec even on systems where posix_spawn() is
+  present, you can use the --disable-posix-spawn option to configure.  Aron
+  Barath <baratharon@caesar.elte.hu> provided the basic implementation.
+
+* Error messages printed when invoking non-existent commands have been cleaned
+  up and made consistent.
+
+* The previous limit of 63 jobs under -jN on MS-Windows is now
+  increased to 4095.  That limit includes the subprocess started by
+  the $(shell) function.
+
+* A new option --no-silent has been added, that cancels the effect of the
+  -s/--silent/--quiet flag.
+
+* A new option -E has been added as a short alias for --eval.
+
+* All wildcard expansion within GNU make, including $(wildcard ...), will sort
+  the results.  See https://savannah.gnu.org/bugs/index.php?52076
+
+* Interoperate with newer GNU libc and musl C runtime libraries.
+
+* Performance improvements provided by Paolo Bonzini <pbonzini@redhat.com>
+
+GNU make Developer News
+
+* Import the GNU standard bootstrap script to replace the hand-rolled
+  "make update" method for building code from a GNU make Git repository.
+
+* Rework the source distribution to move source files into the src/*
+  subdirectory.  This aligns with modern best practices in GNU.
+
+* Replace local portability code with Gnulib content.  Unfortunately due to a
+  problem with Gnulib support for getloadavg, this forces a requirement on
+  Automake 1.16 or above in order to build from Git.  See README.git.

+
+* New variable: $(.SHELLSTATUS) is set to the exit status of the last != or
+  $(shell ...) function invoked in this instance of make.  This will be "0" if
+  successful or not "0" if not successful.  The variable value is unset if no
+  != or $(shell ...) function has been invoked.
+
+* The $(file ...) function can now read from a file with $(file <FILE).
+  The function is expanded to the contents of the file.  The contents are
+  expanded verbatim except that the final newline, if any, is stripped.
+
+* The makefile line numbers shown by GNU make now point directly to the
+  specific line in the recipe where the failure or warning occurred.
+  Sample changes suggested by Brian Vandenberg <phantall@gmail.com>
+
+* The interface to GNU make's "jobserver" is stable as documented in the
+  manual, for tools which may want to access it.
+
+  WARNING: Backward-incompatibility! The internal-only command line option
+  --jobserver-fds has been renamed for publishing, to --jobserver-auth.
+
+* The amount of parallelism can be determined by querying MAKEFLAGS, even when
+  the job server is enabled (previously MAKEFLAGS would always contain only
+  "-j", with no number, when job server was enabled).
+
+* VMS-specific changes:
+
+  * Perl test harness now works.
+
+  * Full support for converting Unix exit status codes to VMS exit status
+    codes.  BACKWARD INCOMPATIBILITY Notice: On a child failure the VMS exit
+    code is now the encoded Unix exit status that Make usually generates, not
+    the VMS exit status of the child.

+* New variables: $(MAKE_TERMOUT) and $(MAKE_TERMERR) are set to non-empty
+  values if stdout or stderr, respectively, are believed to be writing to a
+  terminal.  These variables are exported by default.
+
+* Allow a no-text-argument form of the $(file ...) function.  Without a text
+  argument nothing is written to the file: it is simply opened in the
+  requested mode, then closed again.
+
+* Change the fatal error for mixed explicit and implicit rules, that was
+  introduced in GNU make 3.82, to a non-fatal error.  However, this syntax is
+  still deprecated and may return to being illegal in a future version of GNU
+  make.  Makefiles that rely on this syntax should be fixed.
+  See https://savannah.gnu.org/bugs/?33034
+
+* VMS-specific changes:
+
+  * Support for library files added, including support for using the GNV ar
+    utility.
+
+  * Partial support for properly encoding Unix exit status codes into VMS exit
+    status codes.
+
+    WARNING: Backward-incompatibility! These are different exit status codes
+    than Make exited with in the past.
+
+  * Macros to hold the current make command are set up to translate the
+    argv[0] string to a VMS format path name and prefix it with "MCR " so that
+    the macro has a space in it.
+
+    WARNING: Backward-incompatibility!  This may break complex makefiles that
+    do processing on those macros.  This is unlikely because so much in that
+    area was not and is still not currently working on VMS, it is unlikely to
+    find such a complex makefile, so this is more likely to impact
+    construction of a future makefile.
+
+  * A command file is always used to run the commands for a recipe.
+
+    WARNING: Backward-incompatibility!  Running the make self tests has
+    exposed that there are significant differences in behavior when running
+    with the command file mode.  It is unknown if this will be noticed by most
+    existing VMS makefiles.

+* VMS-specific changes:
+
+  * Michael Gehre (at VISTEC-SEMI dot COM) supplied a fix for a problem with
+    timestamps of object modules in OLBs. The timestamps were not correctly
+    adjusted to GMT based time, if the local VMS time was using a daylight

+
+  * Fix a problem with cached strings, which showed on case-insensitive file
+    systems.
+
+  * Build fixes for const-ified code in VMS specific sources.
+
+  * A note on appending the redirected output. With this change, a simple
+    mechanism is implemented to make ">>" work in action lines. In VMS
+    there is no simple feature like ">>" to have DCL command or program
+    output redirected and appended to a file. GNU make for VMS already
+    implements the redirection of output. If such a redirection is detected,
+    an ">" on the action line, GNU make creates a DCL command procedure to
+    execute the action and to redirect its output. Based on that, now ">>"
+    is also recognized and a similar but different command procedure is
+    created to implement the append. The main idea here is to create a
+    temporary file which collects the output and which is appended to the
+    wanted output file. Then the temporary file is deleted. This is all done
+    in the command procedure to keep changes in make small and simple. This
+    obviously has some limitations but it seems good enough compared with
+    the current ">" implementation. (And in my opinion, redirection is not
+    really what GNU make has to do.) With this approach, it may happen that
+    the temporary file is not yet appended and is left in SYS$SCRATCH.
+    The temporary file names look like "CMDxxxxx.". Any time the created
+    command procedure can not complete, this happens. Pressing Ctrl+Y to
+    abort make is one case. In case of Ctrl+Y the associated command
+    procedure is left in SYS$SCRATCH as well. Its name is CMDxxxxx.COM.
+
+  * Change in the Ctrl+Y handling. The CtrlY handler now uses $delprc to
+    delete all children. This way also actions with DCL commands will be
+    stopped. As before the CtrlY handler then sends SIGQUIT to itself,
+    which is handled in common code.
+
+  * Change in deleteing temporary command files. Temporary command files
+    are now deleted in the vms child termination handler. That deletes
+    them even if a Ctrl+C was pressed.
+
+  * The behavior of pressing Ctrl+C is not changed. It still has only an
+    effect, after the current action is terminated. If that doesn't happen
+    or takes too long, Ctrl+Y should be used instead.

+
+* VMS-specific changes:
+
+  * Fix a problem with automatically remaking makefiles. GNU make uses an

-Build instructions
+  This version of GNU make has been tested on:
+  OpenVMS V8.3/V8.4 (Alpha) and V8.4 (Integrity) AND V7.3 (VAX)
+
+  This version of GNU Make is intended to be run from DCL to run
+  make scripts with a special syntax that is described below.  It
+  likely will not be able to run unmodified Unix makefiles.
+
+  There is an older implementation of GNU Make that was ported to GNV.
+  Work is now in progress to merge that port to get a single version
+  of GNU Make available.  When that merge is done, GNU Make will auto
+  detect that it is running under a Posix shell and then operate as close to
+  GNU Make on Unix as possible.
+
+  The descriptions below are for running GNU make from DCL or equivalent.
+
+Recipe differences:
+-------------------
+
+  GNU Make for OpenVMS can not currently run native Unix make files because of
+  differences in the implementation.
+
+  I am trying to document the current behavior in this section.  This is based
+  on the information in the file NEWS. and running the test suite.
+  TODO: More tests are needed to validate and demonstrate the OpenVMS
+  expected behavior.
+
+  In some cases the older behavior of GNU Make when run from DCL is not
+  compatible with standard makefile behavior.
+
+  This behavior can be changed when running GNU Make from DCL by setting
+  either DCL symbols or logical names of the format GNV$.  The settings
+  are enabled with a string starting with one of '1', 'T', or 'E' for "1",
+  "TRUE", or "ENABLE".  They are disabled with a '0', 'F', or 'D' for "1",
+  "FALSE", or "DISABLE".  If they are not explicitly set to one of these
+  values, then they will be set to their default values.
+
+  The value of the setting DECC$FILENAME_UNIX_REPORT or
+  DECC$FILENAME_UNIX_ONLY will now cause the $(dir x) function to return
+  './' or '[]' as appropriate.
+
+  The name GNV$MAKE_OLD_VMS when enabled will cause GNU Make to behave as
+  much as the older method as can be done with out disabling VMS features.
+  When it is disabled GNU Make have the new behavior which more closely
+  matches Unix Make behavior.
+
+  The default is currently the old behavior when running GNU Make from DCL.
+  In the future this may change.  When running make from GNV Bash the new
+  behavior is the default.
+
+  This is a global setting that sets the default behavior for several other
+  options that can be individually changed.  Many of the individual settings
+  are to make it so that the self tests for GNU Make need less VMS specific
+  modifications.
+
+  The name GNV$MAKE_COMMA when enabled will cause GNU Make to expect a comma
+  for a path separator and use a comma for the separator for a list of files.
+  When disabled, it will cause GNU Make to use a colon for a path separator
+  and a space for the separator for a list of files.  The default is to be
+  enabled if the GNU Make is set to the older behavior.
+
+  The name GNV$MAKE_SHELL_SIM when enabled will cause GNU Make to try to
+  simulate a Posix shell more closely.  The following behaviors occur:
+
+    * Single quotes are converted to double quotes and any double
+      quotes inside of them are doubled.  No environment variable expansion
+      is simulated.
+    * A exit command status will be converted to a Posix Exit
+      where 0 is success and non-zero is failure.
+    * The $ character will cause environment variable expansion.
+    * Environent variables can be set on the command line before a command.
+
+  VMS generally uses logical name search lists instead of path variables
+  where the resolution is handled by VMS independent of the program.  Which
+  means that it is likely that nothing will notice if the default path
+  specifier is changed in the future.
+
+  Currently the built in VMS specific macros and recipes depend on the comma
+  being used as a file list separator.
+  TODO: Remove this dependency as other functions in GNU Make depend on a
+  space being used as a separator.
+
+  The format for recipes are a combination of Unix macros, a subset of
+  simulated UNIX commands, some shell emulation, and OpenVMS commands.
+  This makes the resulting makefiles unique to the OpenVMS port of GNU make.
+
+  If you are creating a OpenVMS specific makefile from scratch, you should also
+  look at MMK (Madgoat Make) available at https://github.com/endlesssoftware/mmk
+  MMK uses full OpenVMS syntax and a persistent subprocess is used for the
+  recipe lines, allowing multiple line rules.
+
+  The default makefile search order is "makefile.vms", "gnumakefile",
+  "makefile".  TODO: See if that lookup is case sensitive.
+
+  When Make is invoked from DCL, it will create a foreign command
+  using the name of executable image, with any facility prefix removed,
+  for the duration of the make program, so it can be used internally
+  to recursively run make().  The macro MAKE_COMMAND will be set to
+  this foreign command.
+
+  When make is launched from an exec*() command from a C program,
+  the foreign command is not created.  The macro MAKE_COMMAND will be
+  set to the actual command passed as argv[0] to the exec*() function.
+
+  If the DCL symbol or logical name GNV$MAKE_USE_MCR exists, then
+  the macro MAKE_COMMAND will be set to be an "MCR" command with the
+  absolute path used by DCL to launch make.  The foreign command
+  will not be created.
+
+  The macro MAKE is set to be the same value as the macro MAKE_COMMAND
+  on all platforms.
+
+  Each recipe command is normally run as a separate spawned processes,
+  except for the cases documented below where a temporary DCL command
+  file may be used.
+
+  BUG: Testing has shown that the commands in the temporary command files
+  are not always created properly.  This issue is still under investigation.
+
+  Any macros marked as exported are temporarily created as DCL symbols
+  for child images to use.  DCL symbol substitution is not done with these
+  commands.
+  Untested: Symbol substitution.
+
+  When a temporary DCL command file is used, DCL symbol substitution
+  will work.
+
+  For VMS 7.3-1 and earlier, command lines are limited to 255 characters
+  or 1024 characters in a command file.
+  For VMS 7.3-2 and later, command lines are limited to 4059 characters
+  or 8192 characters in a command file.
+
+  VMS limits each token of a command line to 256 characters, and limits
+  a command line to 127 tokens.
+
+  Command lines above the limit length are written to a command file
+  in sys$scratch:.
+
+  In order to handle Unix style extensions to VMS DCL, GNU Make has
+  parsed the recipe commands and them modified them as needed.  The
+  parser has been re-written to resolve numerous bugs in handling
+  valid VMS syntax and potential buffer overruns.
+
+  The new parser may need whitespace characters where DCL does not require
+  it, and also may require that quotes are matched were DCL forgives if
+  they are not.  There is a small chance that existing VMS specific makefiles
+  will be affected.
+
+  The '<', '>' was previously implemented using command files.  Now
+  GNU Make will check to see if the is already a VMS "PIPE" command and
+  if it is not, will convert the command to a VMS "PIPE" command.
+
+  The '>>' redirection has been implemented by using a temporary command file.
+  This will be described later.
+
+  The DCL symbol or logical name GNV$MAKE_USE_CMD_FILE when set to a
+  string starting with one of '1','T', or 'E' for "1", "TRUE", or "ENABLE",
+  then temporary DCL command files are always used for running commands.
+
+  Some recipe strings with embedded new lines will not be handled correctly
+  when a command file is used.
+
+  GNU Make generally does text comparisons for the targets and sources.  The
+  make program itself can handle either Unix or OpenVMS format filenames, but
+  normally does not do any conversions from one format to another.
+  TODO: The OpenVMS format syntax handling is incomplete.
+  TODO: ODS-5 EFS support is missing.
+  BUG: The internal routines to convert filenames to and from OpenVMS format
+  do not work correctly.
+
+  Note: In the examples below, line continuations such as a backslash may have
+  been added to make the examples easier to read in this format.
+  BUG: That feature does not completely work at this time.
+
+  Since the OpenVMS utilities generally expect OpenVMS format paths, you will
+  usually have to use OpenVMS format paths for rules and targets.
+  BUG: Relative OpenVMS paths may not work in targets, especially combined
+  with vpaths.  This is because GNU make will just concatenate the directories
+  as it does on Unix.
+
+  The variables $^ and $@ separate files with commas instead of spaces.
+  This is controlled by the name GNV$MAKE_COMMA as documented in the
+  previous section.
+
+  While this may seem the natural thing to do with OpenVMS, it actually
+  causes problems when trying to use other make functions that expect the
+  files to be separated by spaces.  If you run into this, you need the
+  following workaround to convert the output.
+  TODO: Look at have the $^ and $@ use spaces like on Unix and have
+  and easy to use function to do the conversions and have the built
+  in OpenVMS specific recipes and macros use it.
+
+  Example:
+
+comma := ,
+empty :=
+space := $(empty) $(empty)
+
+foo: $(addsuffix .3,$(subs $(comma),$(space),$^)
+
+
+  Makefile variables are looked up in the current environment. You can set
+  symbols or logicals in DCL and evaluate them in the Makefile via
+  $(<name-of-symbol-or-logical>).  Variables defined in the Makefile
+  override OpenVMS symbols/logicals.
+
+  OpenVMS logical and symbols names show up as "environment" using the
+  origin function.  when the "-e" option is specified, the origion function
+  shows them as "environment override".  On Posix the test scripts indicate
+  that they should show up just as "environment".
+
+  When GNU make reads in a symbol or logical name into the environment, it
+  converts any dollar signs found to double dollar signs for convenience in
+  using DCL symbols and logical names in recipes.  When GNU make exports a
+  DCL symbol for a child process, if the first dollar sign found is followed
+  by second dollar sign, then all double dollar signs will be convirted to
+  single dollar signs.
+
+  The variable $(ARCH) is predefined as IA64, ALPHA or VAX respectively.
+  Makefiles for different OpenVMS systems can now be written by checking
+  $(ARCH).  Since IA64 and ALPHA are similar, usually just a check for
+  VAX or not VAX is sufficient.
+
+  You may have to update makefiles that assume VAX if not ALPHA.
+
+ifeq ($(ARCH),VAX)
+  $(ECHO) "On the VAX"
+else
+  $(ECHO) "On the ALPHA  or IA64"
+endif
+
+  Empty commands are handled correctly and don't end in a new DCL process.
+
+  The exit command needs to have OpenVMS exit codes.  To pass a Posix code
+  back to the make script, you need to encode it by multiplying it by 8
+  and then adding %x1035a002 for a failure code and %x1035a001 for a
+  success.  Make will interpret any posix code other than 0 as a failure.
+  TODO: Add an option have simulate Posix exit commands in recipes.
+
+  Lexical functions can be used in pipes to simulate shell file test rules.
+
+  Example:
+
+  Posix:
+b : c ; [ -f $@ ] || echo >> $@
+
+  OpenVMS:
+b : c ; if f$$search("$@") then pipe open/append xx $@ ; write xx "" ; close xx
+
+
+  You can also use pipes and turning messages off to silently test for a
+  failure.
+
+x = %x1035a00a
+
+%.b : %.c
+<tab>pipe set mess/nofac/noiden/nosev/notext ; type $^/output=$@ || exit $(x)
+
+
+Runtime issues:
+
+  The OpenVMS C Runtime has a convention for encoding a Posix exit status into
+  to OpenVMS exit codes.  These status codes will have the hex value of
+  0x35a000.  OpenVMS exit code may also have a hex value of %x10000000 set on
+  them.  This is a flag to tell DCL not to write out the exit code.
+
+  To convert an OpenVMS encoded Posix exit status code to the original code
+  You subtract %x35a000 and any flags from the OpenVMS code and divide it by 8.
+
+  WARNING: Backward-incompatibility!
+  The make program exit now returns the same encoded Posix exit code as on
+  Unix. Previous versions returned the OpenVMS exit status code if that is what
+  caused the recipe to fail.
+  TODO: Provide a way for scripts calling make to obtain that OpenVMS status
+  code.
+
+  Make internally has two error codes, MAKE_FAILURE and MAKE_TROUBLE.  These
+  will have the error "-E-" severity set on exit.
+
+  MAKE_TROUBLE is returned only if the option "-q" or "--question" is used and
+  has a Posix value of 1 and an OpenVMS status of %x1035a00a.
+
+  MAKE_FAILURE has a Posix value of 2 and an OpenVMS status of %x1035a012.
+
+  Output from GNU make may have single quotes around some values where on
+  other platforms it does not.  Also output that would be in double quotes
+  on some platforms may show up as single quotes on VMS.
+
+  There may be extra blank lines in the output on VMS.
+  https://savannah.gnu.org/bugs/?func=detailitem&item_id=41760
+
+  There may be a "Waiting for unfinished jobs..." show up in the output.
+
+  Error messages generated by Make or Unix utilities may slightly vary from
+  Posix platforms.  Typically the case may be different.
+
+  When make deletes files, on posix platforms it writes out 'rm' and the list
+  of files.  On VMS, only the files are writen out, one per line.
+  TODO: VMS
+
+  There may be extra leading white space or additional or missing whitespace
+  in the output of recipes.
+
+  GNU Make uses sys$scratch: for the tempfiles that it creates.
+
+  The OpenVMS CRTL library maps /tmp to sys$scratch if the TMP: logical name
+  does not exist.  As the CRTL may use both sys$scratch: and /tmp internally,
+  if you define the TMP logical name to be different than SYS$SCRATCH:,
+  you may end up with only some temporary files in TMP: and some in SYS$SCRATCH:
+
+  The default include directory for including other makefiles is
+  SYS$SYSROOT:[SYSLIB] (I don't remember why I didn't just use
+  SYS$LIBRARY: instead; maybe it wouldn't work that way).
+  TODO:  A better default may be desired.
+
+  If the device for a file in a recipe does not exist, on OpenVMS an error
+  message of "stat: <file>: no such device or address" will be output.
+
+  Make ignores success, informational, or warning errors (-S-, -I-, or
+  -W-).  But it will stop on -E- and -F- errors. (unless you do something
+  to override this in your makefile, or whatever).
+
+
+Unix compatibilty features:
+---------------------------
+
+  If the command 'echo' is seen, any single quotes on the line will be
+  converted to double quotes.
+
+  The variable $(CD) is implemented as a built in Change Directory
+  command. This invokes the 'builtin_cd'  Executing a 'set default'
+  recipe doesn't do the trick, since it only affects the subprocess
+  spawned for that command.
+
+  The 'builtin_cd' is generally expected to be on its own line.
+  The 'builtin_cd' either from the expansion of $(CD) or directly
+  put in a recipe line will be executed before any other commands in
+  that recipe line.  DCL parameter substitution will not work for the
+  'builtin_cd' command.
+
+  Putting a 'builtin_cd' in a pipeline or an IF-THEN line should not be
+  done because the 'builtin_cd' is always executed
+  and executed first.  The directory change is persistent.
+
+  Unix shell style I/O redirection is supported. You can now write lines like:
+  "<tab>mcr sys$disk:[]program.exe < input.txt > output.txt &> error.txt"
+
+  Posix shells have ":" as a null command.  These are now handled.
+  https://savannah.gnu.org/bugs/index.php?41761
+
+  A note on appending the redirected output.  A simple mechanism is
+  implemented to make ">>" work in action lines. In OpenVMS there is no simple
+  feature like ">>" to have DCL command or program output redirected and
+  appended to a file. GNU make for OpenVMS implements the redirection
+  of ">>" by using a command procedure.
+
+  The current algorithm creates the output file if it does not exist and
+  then uses the DCL open/append to extend it.  SYS$OUTPUT is then directed
+  to that file.
+
+  The implementation supports only one redirected append output to a file
+  and that redirection is done before any other commands in that line
+  are executed, so it redirects all output for that command.
+
+  The older implementation wrote the output to a temporary file in
+  in sys$scratch: and then attempted to append the file to the existing file.
+  The temporary file names looked like "CMDxxxxx.". Any time the created
+  command procedure can not complete, this happens. Pressing Ctrl+Y to
+  abort make is one case.
+
+  In case of Ctrl+Y the associated command procedure is left in SYS$SCRATCH:.
+  The command procedures will be named gnv$make_cmd*.com.
+
+  The CtrlY handler now uses $delprc to delete all children. This way also
+  actions with DCL commands will be stopped. As before the CtrlY handler
+  then sends SIGQUIT to itself, which is handled in common code.
+
+  Temporary command files are now deleted in the OpenVMS child termination
+  handler. That deletes them even if a Ctrl+C was pressed.
+  TODO: Does the previous section about >> leaving files still apply?
+
+  The behavior of pressing Ctrl+C is not changed. It still has only an effect,
+  after the current action is terminated. If that doesn't happen or takes too
+  long, Ctrl+Y should be used instead.
+
+
+Build Options:
+
+  Added support to have case sensitive targets and dependencies but to
+  still use case blind file names. This is especially useful for Java
+  makefiles on VMS:
+
+<TAB>.SUFFIXES :
+<TAB>.SUFFIXES : .class .java
+<TAB>.java.class :
+<TAB><TAB>javac "$<"
+<TAB>HelloWorld.class :      HelloWorld.java
+
+  A new macro WANT_CASE_SENSITIVE_TARGETS in config.h-vms was introduced.
+  It needs to be enabled to get this feature; default is disabled.
+  TODO: This should be a run-time setting based on if the process
+  has been set to case sensitive.
+
+
+Unimplemented functionality:
+
+  The new feature "Loadable objects" is not yet supported. If you need it,
+  please send a change request or submit a bug report.
+
+  The new option --output-sync (-O) is accepted but has no effect: GNU make
+  for OpenVMS does not support running multiple commands simultaneously.
+
+
+Self test failures and todos:
+-----------------------------
+
+  The test harness can not handle testing some of the VMS specific modes
+  because of the features needed for to be set for the Perl to run.
+  Need to find a way to set the VMS features before running make as a
+  child.
+
+  GNU make was not currently translating the OpenVMS encoded POSIX values
+  returned to it back to the Posix values.  I have temporarily modified the
+  Perl test script to compensate for it.  This should be being handled
+  internally to Make.
+  TODO: Verify and update the Perl test script.
+
+  The features/parallelism test was failing. OpenVMS is executing the rules
+  in sequence not in parallel as this feature was not implemented.
+  GNU Make on VMS no longer claims it is implemented.
+  TODO: Implement it.
+
+  Symlink support is not present.  Symlinks are supported by OpenVMS 8.3 and
+  later.
+
+  Error messages should be supressed with the "-" at the beginning of a line.
+  On openVMS they were showing up.  TODO: Is this still an issue?
+
+  The internal vmsify and unixify OpenVMS to/from UNIX are not handling logical
+  names correctly.
+
+
+Build instructions:
 ------------------
+
+  Don't use the HP C V7.2-001 compiler, which has an incompatible change
+  how __STDC__ is defined. This results at least in compile time warnings.

-Changes since GNU make 3.82
----------------------------
 
-Fix build problems.
 
-The new feature "Loadable objects" is not yet supported. If you need it,
-please send a change request or submit a bug report.
+Running the tests:
+------------------
 
-The new option --output-sync (-O) is accepted but has no effect: GNU make
-for VMS does not support running multiple commands simultaneously.
-
-Changes for GNU make 3.82
+  Running the tests on OpenVMS requires the following software to be installed
+  as most of the tests are Unix oriented.
 
-Michael Gehre (at VISTEC-SEMI dot COM) supplied a fix for a problem with
-timestamps of object modules in OLBs. The timestamps were not correctly
-adjusted to GMT based time, if the local VMS time was using a daylight saving
-algorithm and if daylight saving was switched off.
+  * Perl 5.18 or later.
+    https://sourceforge.net/projects/vmsperlkit/files/
+  * GNV 2.1.3 + Updates including a minimum of:
+    * Bash 4.3.30
+    * ld_tools 3.0.2
+    * coreutils 8.21
+   https://sourceforge.net/p/gnv/wiki/InstallingGNVPackages/
+   https://sourceforge.net/projects/gnv/files/
 
-John Eisenbraun (at HP dot COM) supplied fixes and and an enhancement to append
-output redirection in action lines.
+   As the test scripts need to create some foreign commands that persist
+   after the test is run, it is recommend that either you use a subprocess or
+   a dedicated login to run the tests.
 
-Rework of ctrl+c and ctrl+y handling.
+   To get detailed information for running the tests:
 
-Fix a problem with cached strings, which showed on case-insensitive file
-systems.
+   $ set default [.tests]
+   $ @run_make_tests help
 
-Build fixes for const-ified code in VMS specific sources.
+   Running the script with no parameters will run all the tests.
 
-A note on appending the redirected output. With this change, a simple mechanism
-is implemented to make ">>" work in action lines. In VMS there is no simple
-feature like ">>" to have DCL command or program output redirected and appended
-to a file. GNU make for VMS already implements the redirection of output. If
-such a redirection is detected, an ">" on the action line, GNU make creates a
-DCL command procedure to execute the action and to redirect its output. Based
-on that, now ">>" is also recognized and a similar but different command
-procedure is created to implement the append. The main idea here is to create a
-temporary file which collects the output and which is appended to the wanted
-output file. Then the temporary file is deleted. This is all done in the
-command procedure to keep changes in make small and simple. This obviously has
-some limitations but it seems good enough compared with the current ">"
-implementation. (And in my opinion, redirection is not really what GNU make has
-to do.) With this approach, it may happen that the temporary file is not yet
-appended and is left in SYS$SCRATCH. The temporary file names look like
-"CMDxxxxx.". Any time the created command procedure can not complete, this
-happens. Pressing Ctrl+Y to abort make is one case. In case of Ctrl+Y the
-associated command procedure is left in SYS$SCRATCH as well. Its name is
-CMDxxxxx.COM.
+   After the the test script has been run once in a session, assuming
+   that you built make in sys$disk:[make], you can redefined the
+   "bin" logical name as follows:
 
-Change in the Ctrl+Y handling. The CtrlY handler now uses $delprc to delete all
-children. This way also actions with DCL commands will be stopped. As before
-the CtrlY handler then sends SIGQUIT to itself, which is handled in common
-code.
+   $ define bin sys$disk:[make],gnv$gnu:[bin]
 
-Change in deleteing temporary command files. Temporary command files are now
-deleted in the vms child termination handler. That deletes them even if
-a Ctrl+C was pressed.
+   Then you can use Perl to run the scripts.
 
-The behavior of pressing Ctrl+C is not changed. It still has only an effect,
-after the current action is terminated. If that doesn't happen or takes too
-long, Ctrl+Y should be used instead.
-
-Changes for GNU make 3.80
+   $ perl run_make_tests.pl
 
-. In default.c define variable ARCH as IA64 for VMS on Itanium systems.
 
-. In makefile.vms avoid name collision for glob and globfree.
-
-This is the VMS port of GNU Make done by Hartmut.Becker@compaq.com.
+Acknowlegements:
+----------------
 
-It is based on the specific version 3.77k and on 3.78.1. 3.77k was done
-by Klaus Kämpf <kkaempf@rmi.de>, the code was based on the VMS port of
-GNU Make 3.60 by Mike Moretti.
+See NEWS. for details of past changes.
 
-It was ported on OpenVMS/Alpha V7.1, DECC V5.7-006. It was re-build and
-tested on OpenVMS/Alpha V7.2, OpenVMS/VAX 7.1 and 5.5-2. Different
-versions of DECC were used. VAXC was tried: it fails; but it doesn't
-seem worth to get it working. There are still some PTRMISMATCH warnings
-during the compile. Although perl is working on VMS the test scripts
-don't work. The function $shell is still missing.
+  These are the currently known contributers to this port.
 
-There is a known bug in some of the VMS CRTLs. It is in the shipped
-versions of VMS V7.2 and V7.2-1 and in the currently (October 1999)
-available ECOs for VMS V7.1 and newer versions. It is fixed in versions
-shipped with newer VMS versions and all ECO kits after October 1999. It
-only shows up during the daylight saving time period (DST): stat()
-returns a modification time 1 hour ahead. This results in GNU make
-warning messages. For a just created source you will see:
-
- $ gmake x.exe
- gmake.exe;1: *** Warning: File 'x.c' has modification time in the future (940582863 > 940579269)
- cc    /obj=x.obj x.c
- link  x.obj    /exe=x.exe
- gmake.exe;1: *** Warning:  Clock skew detected.  Your build may be incomplete.
-
-
-New in 3.78.1:
-
-Fix a problem with automatically remaking makefiles. GNU make uses an
-execve to restart itself after a successful remake of the makefile. On
-UNIX systems execve replaces the running program with a new one and
-resets all signal handling to the default. On VMS execve creates a child
-process, signal and exit handlers of the parent are still active, and,
-unfortunately, corrupt the exit code from the child. Fix in job.c:
-ignore SIGCHLD.
-
-Added some switches to reflect latest features of DECC. Modifications in
-makefile.vms.
-
-Set some definitions to reflect latest features of DECC. Modifications in
-config.h-vms (which is copied to config.h).
-
-Added extern strcmpi declaration to avoid 'implicitly declared' messages.
-Modification in make.h.
-
-Default rule for C++, conditionals for gcc (GCC_IS_NATIVE) or DEC/Digital/
-Compaq c/c++ compilers. Modifications in default.c.
-
-Usage of opendir() and friends, suppress file version. Modifications in dir.c.
-
-Added VMS specific code to handle ctrl+c and ctrl+y to abort make.
-Modifications in job.c.
-
-Added support to have case sensitive targets and dependencies but to
-still use case blind file names. This is especially useful for Java
-makefiles on VMS:
-
-	.SUFFIXES :
-	.SUFFIXES :	.class .java
-	.java.class :
-		javac "$<
-	HelloWorld.class :      HelloWorld.java
-
-A new macro WANT_CASE_SENSITIVE_TARGETS in config.h-vms was introduced.
-It needs to be enabled to get this feature; default is disabled.  The
-macro HAVE_CASE_INSENSITIVE_FS must not be touched: it is still enabled.
-Modifications in file.c and config.h-vms.
-
-Bootstrap make to start building make is still makefile.com, but make
-needs to be re-made with a make to make a correct version: ignore all
-possible warnings, delete all objects, rename make.exe to a different
-name and run it.
-
-Made some minor modifications to the bootstrap build makefile.com.
-
-This is the VMS port of GNU Make.
-
-It is based on the VMS port of GNU Make 3.60 by Mike Moretti.
-
-This port was done by Klaus Kämpf <kkaempf@rmi.de>
-
-There is first-level support available from proGIS Software, Germany.
-Visit their web-site at http://www.progis.de to get information
-about other vms software and forthcoming updates to gnu make.
-
-New for 3.77:
-
-/bin/sh style I/O redirection is supported. You can now write lines like
-	mcr sys$disk:[]program.exe < input.txt > output.txt &> error.txt
-
-Makefile variables are looked up in the current environment. You can set
-symbols or logicals in DCL and evaluate them in the Makefile via
-$(<name-of-symbol-or-logical>).  Variables defined in the Makefile
-override VMS symbols/logicals !
-
-Functions for file names are working now. See the GNU Make manual for
-$(dir ...)  and $(wildcard ...).  Unix-style and VMS-style names are
-supported as arguments.
-
-The default rules are set up for GNU C. Building an executable from a
-single source file is as easy as 'make file.exe'.
-
-The variable $(ARCH) is predefined as ALPHA or VAX resp. Makefiles for
-different VMS systems can now be written by checking $(ARCH) as in
-  ifeq ($(ARCH),ALPHA)
-    $(ECHO) "On the Alpha"
-  else
-    $(ECHO) "On the VAX"
-  endif
-
-Command lines of excessive length are correctly broken and written to a
-batch file in sys$scratch for later execution. There's no limit to the
-lengths of commands (and no need for .opt files :-) any more.
-
-Empty commands are handled correctly and don't end in a new DCL process.
-
-
-New for 3.76:
-
-John W. Eaton has updated the VMS port to support libraries and VPATH.
-
-
-To build Make, simply type @makefile.  This should compile all the
-necessary files and link Make.  There is also a file called
-makefile.vms.  If you already have GNU Make built you can just use
-Make with this makefile to rebuild.
-
-Here are some notes about GNU Make for VMS:
-
-The cd command is supported if it's called as $(CD). This invokes
-the 'builtin_cd' command which changes the directory.
-Calling 'set def' doesn't do the trick, since a sub-shell is
-spawned for this command, the directory is changed *in this sub-shell*
-and the sub-shell ends.
-
-Libraries are not supported. They were in GNU Make 3.60 but somehow I
-didn't care porting the code. If there is enough interest, I'll do it at
-some later time.
-
-The variable $^ separates files with commas instead of spaces (It's the
-natural thing to do for VMS).
-
-See defaults.c for VMS default suffixes and my definitions for default
-rules and variables.
-
-The shell function is not implemented yet.
-
-Load average routines haven't been implemented for VMS yet.
-
-The default include directory for including other makefiles is
-SYS$SYSROOT:[SYSLIB] (I don't remember why I didn't just use
-SYS$LIBRARY: instead; maybe it wouldn't work that way).
-
-The default makefiles make looks for are: makefile.vms, gnumakefile,
-makefile., and gnumakefile. .
-
-The stat() function and handling of time stamps in VMS is broken, so I
-replaced it with a hack in vmsfunctions.c. I will provide a full rewrite
-somewhere in the future. Be warned, the time resolution inside make is
-less than what vms provides. This might be a problem on the faster Alphas.
-
-You can use a : in a filename only if you precede it with a backslash ('\').
-E.g.- hobbes\:[bogas.files]
-
-Make ignores success, informational, or warning errors (-S-, -I-, or
--W-).  But it will stop on -E- and -F- errors. (unless you do something
-to override this in your makefile, or whatever).
-
-Remote stuff isn't implemented yet.
-
-Multiple line DCL commands, such as "if" statements, must be put inside
-command files.  You can run a command file by using \@.
-
-
-VMS changes made for 3.74.3
-
-Lots of default settings are adapted for VMS. See default.c.
-
-Long command lines are now converted to command files.
-
-Comma (',') as a separator is now allowed. See makefile.vms for an example.

-Building From Git
------------------
+Building From Git for POSIX
+---------------------------
 
-To build GNU make from Git, you will need Autoconf, Automake, and
-Gettext, and any tools that those utilities require (GNU m4, Perl,
-etc.).  See the configure.ac file to find the minimum versions of each
-of these tools.  You will also need a copy of wget.
+To build GNU make from Git on POSIX systems such as GNU/Linux, you will
+need to install the following extra software:
+
+* autoconf
+* automake >= 1.16.1
+* gettext
+* autopoint
+* pkg-config
+* texinfo (for makeinfo)
+* GCC (Clang's GCC emulation is not sufficient)
+* GNU make (POSIX make is not sufficient)
+
+And any tools that those utilities require (GNU m4, etc.)
+
+To run the tests you must install Perl.
+
+To build a release you'll need to install lzip.
+
+GNU make requires gnulib to provide some facilities.  If you want to maintain
+a local installation of gnulib you can set GNULIB_SRCDIR to point to it.
+Otherwise, ./bootstrap will obtain a clone for you.
+
+Unfortunately due to issues with gnulib's getloadavg, you must have automake
+1.16.1 or above.  This version may not yet be available through GNU/Linux
+package managers.  If you need to install from source be sure to set
+ACLOCAL_PATH to point to the pkg-config location (e.g., /usr/share/aclocal).
+
+If you want to build from Git with a non-GCC compiler, add "MAKE_CFLAGS=" to
+your make command line (or at least remove any flags your compiler does not
+support).
 
 When building from Git you must build in the source directory: "VPATH
 builds" from remote directories are not supported.  Once you've created
 a distribution, of course, you can unpack it and do a VPATH build from
 there.
 
-After checking out the code, you will need to perform these steps to get
-to the point where you can run "make".
-
-
- 1) $ autoreconf -i
-
-    This rebuilds all the things that need rebuilding, installing
-    missing files as symbolic links.
-
-    You may get warnings here about missing files like README, etc.
-    Ignore them, they are harmless.
-
-
- 2) $ ./configure
-
-    Generate a Makefile
-
-
- 3) $ make update
-
-    Use wget to retrieve various other files that GNU make relies on,
-    but does not keep in its own source tree.
-
-    NB: You may need GNU make to correctly perform this step; if you use
-    a platform-local make you may get problems with missing files in doc/.
+After checking out the code, you will need to run the bootstrap script:
 
+ $ ./bootstrap
 
 At this point you have successfully brought your Git copy of the GNU
 make source directory up to the point where it can be treated
 more-or-less like the official package you would get from ftp.gnu.org.
 That is, you can just run:
 
-  $ make && make check && make install
+  $ ./configure
+  $ make check
 
-to build and install GNU make.
+to build and test GNU make.
+
+NOTE! This method builds GNU make in "maintainer mode".  Make programs built
+      in this mode it will be slower, possibly MUCH slower: there are various
+      sanity checks enabled.  Further this mode assumes a modern GCC, GNU
+      libc, and well-formed system headers and enables a high level of
+      warnings AND enables -Werror to turn warnings into failures.
+
+      If you want to build from Git with "maintainer mode" disabled, add
+      "MAKE_MAINTAINER_MODE=" to the make command line.  If you want to turn
+      off the extra warning flags, add "MAKE_CFLAGS=" to the make command
+      line.

-/* alloca.c -- allocate automatically reclaimed memory
-   (Mostly) portable public-domain implementation -- D A Gwyn
-
-   This implementation of the PWB library alloca function,
-   which is used to allocate space off the run-time stack so
-   that it is automatically reclaimed upon procedure exit,
-   was inspired by discussions with J. Q. Johnson of Cornell.
-   J.Otto Tennant <jot@cray.com> contributed the Cray support.
-
-   There are some preprocessor constants that can
-   be defined when compiling for your specific system, for
-   improved efficiency; however, the defaults should be okay.
-
-   The general concept of this implementation is to keep
-   track of all alloca-allocated blocks, and reclaim any
-   that are found to be deeper in the stack than the current
-   invocation.  This heuristic does not reclaim storage as
-   soon as it becomes invalid, but it will do so eventually.
-
-   As a special case, alloca(0) reclaims storage without
-   allocating any.  It is a good idea to use alloca(0) in
-   your main control loop, etc. to force garbage collection.  */

-
- Copyright (C) 1991 Free Software Foundation, Inc.
-                    675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the library GPL.  It is
- numbered 2 because it goes with version 2 of the ordinary GPL.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Library General Public License, applies to some
-specially designated Free Software Foundation software, and to any
-other libraries whose authors decide to use it.  You can use it for
-your libraries, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if
-you distribute copies of the library, or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link a program with the library, you must provide
-complete object files to the recipients so that they can relink them
-with the library, after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  Our method of protecting your rights has two steps: (1) copyright
-the library, and (2) offer you this license which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  Also, for each distributor's protection, we want to make certain
-that everyone understands that there is no warranty for this free
-library.  If the library is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original
-version, so that any problems introduced by others will not reflect on
-the original authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that companies distributing free
-software will individually obtain patent licenses, thus in effect
-transforming the program into proprietary software.  To prevent this,
-we have made it clear that any patent must be licensed for everyone's
-free use or not licensed at all.
-
-  Most GNU software, including some libraries, is covered by the ordinary
-GNU General Public License, which was designed for utility programs.  This
-license, the GNU Library General Public License, applies to certain
-designated libraries.  This license is quite different from the ordinary
-one; be sure to read it in full, and don't assume that anything in it is
-the same as in the ordinary license.
-
-  The reason we have a separate public license for some libraries is that
-they blur the distinction we usually make between modifying or adding to a
-program and simply using it.  Linking a program with a library, without
-changing the library, is in some sense simply using the library, and is
-analogous to running a utility program or application program.  However, in
-a textual and legal sense, the linked executable is a combined work, a
-derivative of the original library, and the ordinary General Public License
-treats it as such.
-
-  Because of this blurred distinction, using the ordinary General
-Public License for libraries did not effectively promote software
-sharing, because most developers did not use the libraries.  We
-concluded that weaker conditions might promote sharing better.
-
-  However, unrestricted linking of non-free programs would deprive the
-users of those programs of all benefit from the free status of the
-libraries themselves.  This Library General Public License is intended to
-permit developers of non-free programs to use free libraries, while
-preserving your freedom as a user of such programs to change the free
-libraries that are incorporated in them.  (We have not seen how to achieve
-this as regards changes in header files, but we have achieved it as regards
-changes in the actual functions of the Library.)  The hope is that this
-will lead to faster development of free libraries.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, while the latter only
-works together with the library.
-
-  Note that it is possible for a library to be covered by the ordinary
-General Public License rather than by this special one.
-
-		  GNU LIBRARY GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library which
-contains a notice placed by the copyright holder or other authorized
-party saying it may be distributed under the terms of this Library
-General Public License (also called "this License").  Each licensee is
-addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also compile or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    c) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    d) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the source code distributed need not include anything that is normally
-distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Library General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-     Appendix: How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Library General Public
-    License as published by the Free Software Foundation; either
-    version 2 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Library General Public License for more details.
-
-    You should have received a copy of the GNU Library General Public
-    License along with this library; if not, write to the Free
-    Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
-  <signature of Ty Coon>, 1 April 1990
-  Ty Coon, President of Vice
-
-That's all there is to it!

-	version
-
-1999-09-11  Paul Eggert  <eggert@twinsun.com>
-
-	* glob.h (glob): If #defining to glob64, do this before

-
-1999-09-08  Eli Zaretskii  <eliz@is.elta.co.il>
-
-	* glob.c (prefix_array) [__MSDOS__,WINDOWS32]: Keep the trailing

-	folks (Ulrich Drepper).  Had to re-integrate some DOS/Windows
-	code.
-
-1998-07-10  Paul D. Smith  <psmith@gnu.org>
-
-	* glob.c (glob_in_dir): If no meta chars exist in PATTERN and
-	GLOB_NOCHECK is present, don't look for the file--whether it's
-	found or not, we'll always return it, so why bother searching?
-
-	Also, if we are searching and there are no meta chars, don't
-	bother trying fnmatch() if the strcmp() fails.
-
-1998-05-30  Eli Zaretskii  <eliz@is.elta.co.il>
-
-	* glob.c (glob) [__MSDOS__, WINDOWS32]: Compute the directory and

-	spec.  Disallow wildcards in the drive spec.  Prevent recursion
-	when dirname is of the form "d:/" or "d:".
-	(prefix_array) [__MSDOS__, WINDOWS32]: Don't append a slash to
-	"d:/" and "d:".
-
-1998-05-13  Paul D. Smith  <psmith@gnu.org>

-	* SMakefile, Makefile.ami, glob.c, glob.h, fnmatch.c: Updated from
-	the latest glibc version.
-
-1998-04-17  Paul D. Smith  <psmith@gnu.org>

-	* configure.in: Create a config.h file instead of setting things
-	on the compile line.  This is because when build.sh runs it merely
-	passes -DHAVE_CONFIG_H to the glob files, just as it does to the
-	make files.
-	* config.h.in: Created by autoheader.
-
-Tue Aug 12 10:52:34 1997  Paul D. Smith  <psmith@baynetworks.com>

-
-	* glob: Updates from latest GNU libc glob code.
-
-	* glob.c,glob.h,fnmatch.h: Change all WIN32 references to WINDOWS32.
-
-	* glob.h: OSF4 defines macros in such a way that GLOB_ALTDIRFUNC
-	is not defined.  Added a test to the #if which defines it if
-	_GNU_SOURCE is defined; that's set by both glob.c and GNU make.
-
-	* glob.c: SunOS4 w/ cc needs #include <stdio.h>, since assert.h
-	requires stderr but doesn't include stdio.h :-/.
-	(next_brace_sub): De-protoize function definition.
-	(glob): Cast __alloca(); on SunOS4 it uses the default return type
-	of int.
-	(glob): Irix defines getlogin_r() to return a char*; move the
-	extern for that into the _LIBC area since it isn't used except in
-	LIBC anyway.  Likewise, move extern getlogin() into the "else".

-Sat Jul 20 21:55:31 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
-
-	Win32 hacks from <Rob_Tulloh@tivoli.com>.
-	* posix/glob.c [WIN32]: Don't include <pwd.h>; don't use d_ino;
-	use void * for my_realloc; include <malloc.h> for alloca.
-	(glob) [WIN32]: Use "c:/users/default" for ~ if no HOME variable.
-	* posix/fnmatch.h [WIN32]: Use prototypes even if [!__STDC__].
-	* posix/glob.h: Likewise.
-
-Fri Jul 19 16:56:41 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
-
-	* posix/glob.h [!_AMIGA && !VMS]: Check this instead of just [!_AMIGA]
-	for `struct stat;' forward decl.
-
-Sat Jun 22 10:44:09 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
-
-	* posix/glob.c: Include <alloca.h> only [HAVE_ALLOCA_H], not [sparc].
-
-Fri Jun 21 00:27:51 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
-
-	* posix/fnmatch.c (fnmatch): Fix \*[*?]+ case to increment name ptr
-	only for ?s, not for *s.  Fix from Chet Ramey.
