-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 4.4 (31 Oct 2022)
 
 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=106&set=custom
+https://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id=109&set=custom
+
+* WARNING: Deprecation!
+  The following systems are deprecated in this release:
+    - OS/2 (EMX)
+    - AmigaOS
+    - Xenix
+    - Cray
+  In the NEXT release of GNU Make, support for these systems will be removed.
+  If you want to see them continue to be supported, contact <bug-make@gnu.org>.
+
+* WARNING: Future backward-incompatibility!
+  In the NEXT release of GNU Make, pattern rules will implement the same
+  behavior change for multiple targets as explicit grouped targets, below: if
+  any target of the rule is needed by the build, the recipe will be invoked if
+  any target of the rule is missing or out of date.  During testing some
+  makefiles were found to contain pattern rules that do not build all targets;
+  this can cause issues so we are delaying this change for one release cycle
+  to allow these makefiles to be updated.  GNU Make shows a warning if it
+  detects this situation: "pattern recipe did not update peer target".
+
+* WARNING: Backward-incompatibility!
+  GNU Make now uses temporary files in more situations than previous releases.
+  If your build system sets TMPDIR (or TMP or TEMP on Windows) and deletes the
+  contents during the build, or uses restrictive permissions, this may cause
+  problems.  You can choose an alternative temporary directory only for use by
+  GNU Make by setting the new MAKE_TMPDIR environment variable before invoking
+  make.  Note that this value CANNOT be set inside the makefile, since make
+  needs to find its temporary directory before the makefiles are parsed.
+
+* WARNING: Backward-incompatibility!
+  Previously each target in a explicit grouped target rule was considered
+  individually: if the targets needed by the build were not out of date the
+  recipe was not run even if other targets in the group were out of date.  Now
+  if any of the grouped targets are needed by the build, then if any of the
+  grouped targets are out of date the recipe is run and all targets in the
+  group are considered updated.
+
+* WARNING: Backward-incompatibility!
+  Previously if --no-print-directory was seen anywhere in the environment or
+  command line it would take precedence over any --print-directory.  Now, the
+  last setting of directory printing options seen will be used, so a command
+  line such as "--no-print-directory -w" _will_ show directory entry/exits.
+
+* WARNING: Backward-incompatibility!
+  Previously the order in which makefiles were remade was not explicitly
+  stated, but it was (roughly) the inverse of the order in which they were
+  processed by make.  In this release, the order in which makefiles are
+  rebuilt is the same order in which make processed them, and this is defined
+  to be true in the GNU Make manual.
+
+* WARNING: Backward-incompatibility!
+  Previously only simple (one-letter) options were added to the MAKEFLAGS
+  variable that was visible while parsing makefiles.  Now, all options are
+  available in MAKEFLAGS.  If you want to check MAKEFLAGS for a one-letter
+  option, expanding "$(firstword -$(MAKEFLAGS))" is a reliable way to return
+  the set of one-letter options which can be examined via findstring, etc.
+
+* WARNING: Backward-incompatibility!
+  Previously makefile variables marked as export were not exported to commands
+  started by the $(shell ...) function.  Now, all exported variables are
+  exported to $(shell ...).  If this leads to recursion during expansion, then
+  for backward-compatibility the value from the original environment is used.
+  To detect this change search for 'shell-export' in the .FEATURES variable.
+
+* WARNING: New build requirement
+  GNU Make utilizes facilities from GNU Gnulib: Gnulib requires certain C99
+  features in the C compiler and so these features are required by GNU Make:
+  https://www.gnu.org/software/gnulib/manual/html_node/C99-features-assumed.html
+  The configure script should verify the compiler has these features.
+
+* New feature: The .WAIT special target
+  If the .WAIT target appears between two prerequisites of a target, then
+  GNU Make will wait for all of the targets to the left of .WAIT in the list
+  to complete before starting any of the targets to the right of .WAIT.
+  This feature is available in some other versions of make, and it will be
+  required by an upcoming version of the POSIX standard for make.
+  Different patches were made by Alexey Neyman <alex.neyman@auriga.ru> (2005)
+  and Steffen Nurpmeso <steffen@sdaoden.eu> (2020) that were useful but the
+  result is a different implementation (closer to Alexey's idea).
+
+* New feature: .NOTPARALLEL accepts prerequisites
+  If the .NOTPARALLEL special target has prerequisites then all prerequisites
+  of those targets will be run serially (as if .WAIT was specified between
+  each prerequisite).
+
+* New feature: The .NOTINTERMEDIATE special target
+  .NOTINTERMEDIATE disables intermediate behavior for specific files, for all
+  files built using a pattern, or for the entire makefile.
+  Implementation provided by Dmitry Goncharov <dgoncharov@users.sf.net>
+
+* New feature: The $(let ...) function
+  This function allows user-defined functions to define a set of local
+  variables: values can be assigned to these variables from within the
+  user-defined function and they will not impact global variable assignments.
+  Implementation provided by Jouke Witteveen <j.witteveen@gmail.com>
+
+* New feature: The $(intcmp ...) function
+  This function allows conditional evaluation controlled by a numerical
+  comparison.
+  Implementation provided by Jouke Witteveen <j.witteveen@gmail.com>
+
+* New feature: Improved support for -l / --load-average
+  On systems that provide /proc/loadavg (Linux), GNU Make will use it to
+  determine the number of runnable jobs and use this as the current load,
+  avoiding the need for heuristics.
+  Implementation provided by Sven C. Dack <sdack@gmx.com>
+
+* New feature: The --shuffle command line option
+  This option reorders goals and prerequisites to simulate non-determinism
+  that may be seen using parallel build.  Shuffle mode allows a form of "fuzz
+  testing" of parallel builds to verify that all prerequisites are correctly
+  described in the makefile.
+  Implementation provided by Sergei Trofimovich <siarheit@google.com>
+
+* New feature: The --jobserver-style command line option and named pipes
+  A new jobserver method is used on systems where mkfifo(3) is supported.
+  This solves a number of obscure issues related to using the jobserver
+  and recursive invocations of GNU Make.  This change means that sub-makes
+  will connect to the jobserver even if they are not marked as recursive.
+  It also means that other tools that want to participate in the jobserver
+  will need to be enhanced as described in the GNU Make manual.
+  You can force GNU Make to use the simple pipe-based jobserver (perhaps if
+  you are integrating with other tools or older versions of GNU Make) by
+  adding the '--jobserver-style=pipe' option to the command line of the
+  top-level invocation of GNU Make, or via MAKEFLAGS or GNUMAKEFLAGS.
+  To detect this change search for 'jobserver-fifo' in the .FEATURES variable.
+
+* Some POSIX systems (*BSD) do not allow locks to be taken on pipes, which
+  caused the output sync feature to not work properly there.  Also multiple
+  invocations of make redirecting to the same output file (e.g., /dev/null)
+  would cause hangs.  Instead of locking stdout (which does have some useful
+  performance characteristics, but is not portable) create a temporary file
+  and lock that.  Windows continues to use a mutex as before.
+
+* GNU Make has sometimes chosen unexpected, and sub-optimal, chains of
+  implicit rules due to the definition of "ought to exist" in the implicit
+  rule search algorithm, which considered any prerequisite mentioned in the
+  makefile as "ought to exist".  This algorithm has been modified to prefer
+  prerequisites mentioned explicitly in the target being built and only if
+  that results in no matching rule, will GNU Make consider prerequisites
+  mentioned in other targets as "ought to exist".
+  Implementation provided by Dmitry Goncharov <dgoncharov@users.sf.net>
+
+* GNU Make was performing secondary expansion of all targets, even targets
+  which didn't need to be considered during the build.  In this release
+  only targets which are considered will be secondarily expanded.
+  Implementation provided by Dmitry Goncharov <dgoncharov@users.sf.net>
+
+* If the MAKEFLAGS variable is modified in a makefile, it will be re-parsed
+  immediately rather than after all makefiles have been read.  Note that
+  although all options are parsed immediately, some special effects won't
+  appear until after all makefiles are read.
+
+* The -I option accepts an argument "-" (e.g., "-I-") which means "reset the
+  list of search directories to empty".  Among other things this can be used
+  to prevent GNU Make from searching in its default list of directories.
+
+* New debug option "print" will show the recipe to be run, even when silent
+  mode is set, and new debug option "why" will show why a target is rebuilt
+  (which prerequisites caused the target to be considered out of date).
+  Implementation provided by David Boyce <David.S.Boyce@gmail.com>
+
+* The existing --trace option is made equivalent to --debug=print,why
+
+* Target-specific variables can now be marked "unexport".
+
+* Exporting / unexporting target-specific variables is handled correctly, so
+  that the attribute of the most specific variable setting is used.
+
+* Special targets like .POSIX are detected upon definition, ensuring that any
+  change in behavior takes effect immediately, before the next line is parsed.
+
+* When the pipe-based jobserver is enabled and GNU Make decides it is invoking
+  a non-make sub-process and closes the jobserver pipes, it will now add a new
+  option to the MAKEFLAGS environment variable that disables the jobserver.
+  This prevents sub-processes that invoke make from accidentally using other
+  open file descriptors as jobserver pipes.  For more information see
+  https://savannah.gnu.org/bugs/?57242 and https://savannah.gnu.org/bugs/?62397
+
+* A long-standing issue with the directory cache has been resolved: changes
+  made as a side-effect of some other target's recipe are now noticed as
+  expected.
+
+* GNU Make can now be built for MS-Windows using the Tiny C tcc compiler.
+  Port provided by Christian Jullien <eligis@orange.fr>

+Version 4.3 (19 Jan 2020)
+
+A complete list of bugs fixed in this version is available here:
+
+https://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!
+  Previously using the .SILENT pseudo-target in a makefile would force all
+  sub-makes to be invoked with the '-s' option, effectively making all
+  sub-makes silent as well.  In this release .SILENT only affects the current
+  invocation of make.  A side-effect of this is that .SILENT will no longer
+  enable the --no-print-directory option, which using -s will do.
+
+* NOTE: Deprecated behavior.
+  Contrary to the documentation, suffix rules with prerequisites are being
+  treated BOTH as simple targets AND as pattern rules.  Further, the
+  prerequisites are ignored by the pattern rules.  POSIX specifies that in
+  order to be a suffix rule there can be no prerequisites defined.  In this
+  release if POSIX mode is enabled then rules with prerequisites cannot be
+  suffix rules.  If POSIX mode is not enabled then the previous behavior is
+  preserved (a pattern rule with no extra prerequisites is created) AND a
+  warning about this behavior is generated:
+    warning: ignoring prerequisites on suffix rule definition
+  The POSIX behavior will be adopted as the only behavior in a future release
+  of GNU make so please resolve any warnings.
+
+* 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.
+  Implementation contributed by Christof Warlich <cwarlich@gmx.de>
+
+* 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.
+  Implementation contributed by Aron Barath <baratharon@caesar.elte.hu>
+
+* 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.

-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 and gnulib.
+To build GNU Make from Git on POSIX systems such as GNU/Linux, you will
+need to install the following extra software:
+
+* autoconf >= 2.69
+* automake >= 1.16.1
+* gettext
+* autopoint
+* pkg-config
+* texinfo (for makeinfo)
+* GCC
+* 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.
+
+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".
+After checking out the code, you will need to run the bootstrap script:
 
- 1) $ autoreconf -i
+ $ ./bootstrap
 
-    This rebuilds all the things that need rebuilding, installing
-    missing files as symbolic links.
+Alternatively you can just pull content from remote locations with:
 
-    You may get warnings here about missing files like README, etc.
-    Ignore them, they are harmless.
+ $ ./autopull.sh
 
- 2) $ ./configure
+And/or just re-generate auto-generatable files with:
 
-    Generate a Makefile
+ $ ./autogen.sh
 
- 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/.
+(Running ./bootstrap does both in one step.)
 
 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.
+
+      For example:
+        $ ./configure
+        $ make check MAKE_MAINTAINER_MODE= MAKE_CFLAGS=

+* Alternate Configurations:
+  The maintMakefile has a rule for running configure with various different
+  options, with and without packages.  Run:
+
+    make check-alt-config
+
+* Valgrind:
+  You can run all tests under valgrind by passing the -memcheck option:
+
+    (cd tests && ./run_make_tests -make ../make -memcheck)
+
+  Note, this is slow!  Also some tests will fail because of invoking valgrind.

+  which one is wrong: I haven't looked at them closely.

   $ make distcheck

+Downloading
+-----------
+
+GNU Make can be obtained in many different ways.  See a description here:
+
+  https://www.gnu.org/software/software.html
+
+
+Documentation
+-------------
+
+GNU Make is fully documented in the GNU Make manual, which is contained in
+this distribution as the file make.texi.  You can also find on-line and
+preformatted (PostScript and DVI) versions at the FSF's web site.  There is
+information there about ordering hardcopy documentation.

+
+
+Development
+-----------
+
+GNU Make development is hosted by Savannah, the FSF's online development
+management tool.  Savannah is here:
+
+  https://savannah.gnu.org
+
+And the GNU Make development page is here:
+
+  https://savannah.gnu.org/projects/make/
+
+You can find most information concerning the development of GNU Make at
+this site.
+
+
+Regression Tests
+----------------
+
+GNU Make contains a suite of regression tests.  To run them use "make check"
+after building GNU Make.  If they fail a tar package will be created
+containing useful information, which can be emailed (as an attachment) to
+the <bug-make@gnu.org> mailing list.
+
+Please note that since these tests rely on known-good-output comparisons,
+they can show spurious failures on some systems (particularly non-POSIX systems
+such as Windows).
+
+
+Bug Reporting
+-------------
+
+If you need help using GNU Make, try asking on <help-make@gnu.org>.
+
+If you found a bug, you can send a bug reports to <bug-make@gnu.org>.
+Please see the section of the GNU Make manual entitled 'Problems and Bugs'
+for information on submitting useful and complete bug reports.
+
+You do not need to subscribe to these lists first.
+
+You can also use the online bug tracking system in the Savannah GNU Make
+project to submit new problem reports or search for existing ones:
+
+  https://savannah.gnu.org/bugs/?group=make
+
+We prefer to use the bug tracking system ONLY for bugs or enhancements,
+not for help requests: please use the mailing lists to get help.
+
+
+Submitting Patches
+------------------
+
+If you'd like to propose a change to GNU Make, you can provide a patch with
+your changes.  If you are making your changes in a Git workspace you can run
+"git format-patch" to create a patch file.  If not, you can use the diff(1)
+utility to create a patch file; please use "diff -u".
+
+Once you have a patch you can submit it in any of these ways:
+
+  * Create a bug on Savannah and add the patch as an attachment:
+      https://savannah.gnu.org/bugs/?group=make&func=additem
+
+  * Send the patch via email to <bug-make@gnu.org>: be sure to add it as an
+    attachment to avoid interference by email processors.
+
+All non-trivial changes require FSF copyright paperwork to be completed
+before they can be accepted.  Contact <bug-make@gnu.org> for help.
+
+
+Git Access
+----------
+
+The GNU Make source repository is available via Git from the GNU Savannah Git
+server; look here for details:
+
+  https://savannah.gnu.org/git/?group=make
+
+Please note: you won't be able to build GNU Make from Git without installing
+appropriate maintainer's tools, such as GNU m4, automake, autoconf, Perl, GNU
+make, and GCC.
+
+See the README.git file for instructions on how to build GNU Make once these
+tools are available.  We make no guarantees about the contents or quality of
+the latest code in the Git repository: it is not unheard of for code that is
+known to be broken to be checked in.  Use at your own risk.
+
+
+System-specific Notes
+---------------------
+
+It has been reported that the XLC 1.2 compiler on AIX 3.2 is buggy such
+that if you compile make with 'cc -O' on AIX 3.2, it will not work
+correctly.  It is said that using 'cc' without '-O' does work.
+
+The standard /bin/sh on SunOS 4.1.3_U1 and 4.1.4 is broken and cannot be
+used to configure GNU Make.  Please install a different shell such as
+bash or pdksh in order to run "configure".  See this message for more
+information:
+  https://mail.gnu.org/archive/html/bug-autoconf/2003-10/msg00190.html
+
+One area that is often a problem in configuration and porting is the code
+to check the system's current load average.  To make it easier to test and
+debug this code, you can do 'make check-loadavg' to see if it works
+properly on your system.  (You must run 'configure' beforehand, but you
+need not build 'make' itself to run this test.)
+
+Another potential source of porting problems is the support for large
+files (LFS) in configure for those operating systems that provide it.
+Please report any bugs that you find in this area.  If you run into
+difficulties, then as a workaround you should be able to disable LFS by
+adding the '--disable-largefile' option to the 'configure' script.
+
+On systems that support micro- and nano-second timestamp values and
+where stat(2) provides this information, GNU Make will use it when
+comparing timestamps to get the most accurate possible result.  However,
+note that many current implementations of tools that *set* timestamps do
+not preserve micro- or nano-second granularity.  This means that "cp -p"
+and other similar tools (tar, etc.) may not exactly duplicate timestamps
+with micro- and nano-second granularity on some systems.  If your build
+system contains rules that depend on proper behavior of tools like "cp
+-p", you should consider using the .LOW_RESOLUTION_TIME pseudo-target to
+force make to treat them properly.  See the manual for details.
+
+

+    information.
+
+    The Cygwin project maintains its own port of GNU Make.  That port may have
+    patches which are not present in this version.  If you are using Cygwin
+    you should use their version of GNU Make, and if you have questions about
+    it you should start by asking on those mailing lists and forums.
+
+Please note there are two _separate_ ports of GNU Make for Microsoft
+systems: a native Windows tool built with (for example) MSVC or Cygwin,
+and a DOS-based tool built with DJGPP.  Please be sure you are looking
+at the right README!

-/* 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.  */

+                           you want to use these sources.
+  GNULIB_REFDIR            Specifies the local directory where a gnulib
+                           repository (with a .git subdirectory) resides.
+                           Use this if you already have gnulib sources
+                           and history on your machine, and do not want
+                           to waste your bandwidth downloading them again.
+  GNULIB_URL               Cloneable URL of the gnulib repository.

+                           \$GNULIB_SRCDIR or the --gnulib-srcdir option

+If the file bootstrap.conf exists in the same directory as this script, its

+
+For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
+are honored.
+
+Gnulib sources can be fetched in various ways:
+
+ * If the environment variable GNULIB_SRCDIR is set (either as an
+   environment variable or via the --gnulib-srcdir option), then sources
+   are fetched from that local directory.  If it is a git repository and
+   the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+   then that revision is checked out.
+
+ * Otherwise, if this package is in a git repository with a 'gnulib'
+   submodule configured, then that submodule is initialized and updated
+   and sources are fetched from there.  If GNULIB_REFDIR is set (either
+   as an environment variable or via the --gnulib-refdir option) and is
+   a git repository, then it is used as a reference.
+
+ * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
+   are cloned into that directory using git from \$GNULIB_URL, defaulting
+   to $default_gnulib_url.
+   If the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+   then that revision is checked out.
+
+ * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
+   used.  If it is a git repository and the configuration variable
+   GNULIB_REVISION is set in bootstrap.conf, then that revision is
+   checked out.
+
+If you maintain a package and want to pin a particular revision of the
+Gnulib sources that has been tested with your package, then there are
+two possible approaches: either configure a 'gnulib' submodule with the
+appropriate revision, or set GNULIB_REVISION (and if necessary
+GNULIB_URL) in bootstrap.conf.
+
+Running without arguments will suffice in most cases.

+Optional environment variables:
+  GNULIB_SRCDIR            Specifies the local directory where gnulib
+                           sources reside.  Use this if you already
+                           have gnulib sources on your machine, and
+                           do not want to waste your bandwidth downloading
+                           them again.
+  GNULIB_URL               Cloneable URL of the gnulib repository.
+
+Options:
+  --gnulib-srcdir=DIRNAME  specify the local directory where gnulib
+                           sources reside.  Use this if you already
+                           have gnulib sources on your machine, and
+                           you want to use these sources.  Defaults
+                           to \$GNULIB_SRCDIR
+  --gnulib-refdir=DIRNAME  specify the local directory where a gnulib
+                           repository (with a .git subdirectory) resides.
+                           Use this if you already have gnulib sources
+                           and history on your machine, and do not want
+                           to waste your bandwidth downloading them again.
+                           Defaults to \$GNULIB_REFDIR
+  --bootstrap-sync         if this bootstrap script is not identical to
+                           the version in the local gnulib sources,
+                           update this script, and then restart it with
+                           /bin/sh or the shell \$CONFIG_SHELL
+  --no-bootstrap-sync      do not check whether bootstrap is out of sync
+  --copy                   copy files instead of creating symbolic links
+  --force                  attempt to bootstrap even if the sources seem
+                           not to have been checked out
+  --no-git                 do not use git to update gnulib.  Requires that
+                           \$GNULIB_SRCDIR or the --gnulib-srcdir option
+                           points to a gnulib repository with the correct
+                           revision

+If the file bootstrap.conf exists in the same directory as this script, its
+contents are read as shell variables to configure the bootstrap.
+
+For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
+are honored.
+
+Gnulib sources can be fetched in various ways:
+
+ * If the environment variable GNULIB_SRCDIR is set (either as an
+   environment variable or via the --gnulib-srcdir option), then sources
+   are fetched from that local directory.  If it is a git repository and
+   the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+   then that revision is checked out.
+
+ * Otherwise, if this package is in a git repository with a 'gnulib'
+   submodule configured, then that submodule is initialized and updated
+   and sources are fetched from there.  If GNULIB_REFDIR is set (either
+   as an environment variable or via the --gnulib-refdir option) and is
+   a git repository, then it is used as a reference.
+
+ * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
+   are cloned into that directory using git from \$GNULIB_URL, defaulting
+   to $default_gnulib_url.
+   If the configuration variable GNULIB_REVISION is set in bootstrap.conf,
+   then that revision is checked out.
+
+ * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
+   used.  If it is a git repository and the configuration variable
+   GNULIB_REVISION is set in bootstrap.conf, then that revision is
+   checked out.
+
+If you maintain a package and want to pin a particular revision of the
+Gnulib sources that has been tested with your package, then there are
+two possible approaches: either configure a 'gnulib' submodule with the
+appropriate revision, or set GNULIB_REVISION (and if necessary
+GNULIB_URL) in bootstrap.conf.
+
+Running without arguments will suffice in most cases.

+
+The gnulib project provides a fantastic array of modules that can support both
+POSIX and also extended features for GNU software.
+
+Unfortunately using it in GNU make is problematic: GNU make is a foundational
+utility (if you don't have a "make" program you pretty much can't build any
+software), one of our goals in GNU make is to provide scripts (e.g.,
+"build.sh") that will build GNU make without needing an instance of make.
+
+Instead of running "./configure && make", you should be able to run
+"./configure && ./build.sh" and get a build of GNU make as a result.
+
+However, more and more gnulib modules are relying not on M4 macros and
+the configure script to manage their configuration, but in addition special
+makefile recipes that perform various post-configure operations.  Since we
+don't have an instance of "make", we cannot use these modules as-is.
+
+There are various options we could choose for solving this:
+
+- Avoid gnulib modules and write our own portability interfaces.
+  I really am not too excited about this.
+
+- Give up on "build.sh" and require users to already have "make".
+  The argument here is that you must already have a compiler, and it couldn't
+  have been built without "make", and/or if you build it with a cross-compiler
+  then you should be able to use that cross-development environment to build
+  GNU make as well.
+
+- Provide a "mini-make" with just enough functionality to support the gnulib
+  makefiles but no extra features, that didn't need any complex gnulib
+  modules.  As with the first option, I'm not too excited about this.
+
+Although arguably the second option is the sane one, I'm not really excited
+about any of them for the time being.  So I elected to try something between
+the first and second options:
+
+The gnulib-port Git branch will contain unmodified copies of gnulib modules
+that we want to use with GNU make.  From there, we merge them into the main
+Git branch then modify / simplify them to avoid unnecessary extra modules and
+allow "build.sh" to be used.
+
+By keeping the unmodified versions on the gnulib-port branch, we enable Git
+merge facilities to merge in new versions as follows:
+
+* Check out the gnulib-port branch
+
+* Update its content with any updates to gnulib modules.  Something like:
+  (
+    cd gl \
+      && find */. -type f \
+        | while read fn; do
+            test -f "$GNULIB_SRCDIR/$fn" && cp "$GNULIB_SRCDIR/$fn" "$fn"
+          done
+  )
+
+* Commit the changes _without modification_
+
+* Check out the main branch
+
+* Run "git merge --no-ff gnulib-port" to merge in the changes
+
+* Resolve any conflicts and commit the merge.

-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!

-	* config.h.in: Created by autoheader.
-
-Tue Aug 12 10:52:34 1997  Paul D. Smith  <psmith@baynetworks.com>
-
-	* configure.in: Require autoconf 2.12.
-
-	* 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.

-
-   Read a token.  As long as there's no token available we'll block.  We
-   enable interruptible system calls before the read(2) so that if we get a

-   There is one other twist: there is a span between the time reap_children()
-   does its last check for dead children and the time the read(2) call is
-   entered, below, where if a child dies we won't notice.  This is extremely
-   serious as it could cause us to deadlock, given the right set of events.
-
-   To avoid this, we do the following: before we reap_children(), we dup(2)
-   the read FD on the jobserver pipe.  The read(2) call below uses that new
-   FD.  In the signal handler, we close that FD.  That way, if a child dies
-   during the section mentioned above, the read(2) will be invoked with an
