-@node Standard Targets
-@section Standard Targets for Users
-
-All GNU programs should have the following targets in their Makefiles:
-
-@table @samp
-@item all
-Compile the entire program.  This should be the default target.  This
-target need not rebuild any documentation files; Info files should
-normally be included in the distribution, and DVI files should be made
-only when explicitly asked for.
-
-@item install
-Compile the program and copy the executables, libraries, and so on to
-the file names where they should reside for actual use.  If there is a
-simple test to verify that a program is properly installed, this target
-should run that test.
-
-If possible, write the @code{install} target rule so that it does not
-modify anything in the directory where the program was built, provided
-@samp{make all} has just been done.  This is convenient for building the
-program under one user name and installing it under another.
-
-The commands should create all the directories in which files are to be
-installed, if they don't already exist.  This includes the directories
-specified as the values of the variables @code{prefix} and
-@code{exec_prefix}, as well as all subdirectories that are needed.
-One way to do this is by means of an @code{installdirs} target
-as described below.
-
-Use @samp{-} before any command for installing a man page, so that
-@code{make} will ignore any errors.  This is in case there are systems
-that don't have the Unix man page documentation system installed.
-
-The way to install Info files is to copy them into @file{$(infodir)}
-with @code{$(INSTALL_DATA)} (@pxref{Command Variables}), and then run
-the @code{install-info} program if it is present.  @code{install-info}
-is a script that edits the Info @file{dir} file to add or update the
-menu entry for the given Info file; it will be part of the Texinfo package.
-Here is a sample rule to install an Info file:
-
-@comment This example has been carefully formatted for the Make manual.
-@comment Please do not reformat it without talking to roland@gnu.ai.mit.edu.
-@smallexample
-$(infodir)/foo.info: foo.info
-# There may be a newer info file in . than in srcdir.
-        -if test -f foo.info; then d=.; \
-         else d=$(srcdir); fi; \
-        $(INSTALL_DATA) $$d/foo.info $@@; \
-# Run install-info only if it exists.
-# Use `if' instead of just prepending `-' to the
-# line so we notice real errors from install-info.
-# We use `$(SHELL) -c' because some shells do not
-# fail gracefully when there is an unknown command.
-        if $(SHELL) -c 'install-info --version' \
-           >/dev/null 2>&1; then \
-          install-info --infodir=$(infodir) $$d/foo.info; \
-        else true; fi
-@end smallexample
-
-@item uninstall
-Delete all the installed files that the @samp{install} target would
-create (but not the noninstalled files such as @samp{make all} would
-create).
-
-This rule should not modify the directories where compilation is done,
-only the directories where files are installed.
-
-@comment The gratuitous blank line here is to make the table look better
-@comment in the printed Make manual.  Please leave it in.
-@item clean
-
-Delete all files from the current directory that are normally created by
-building the program.  Don't delete the files that record the
-configuration.  Also preserve files that could be made by building, but
-normally aren't because the distribution comes with them.
-
-Delete @file{.dvi} files here if they are not part of the distribution.
-
-@item distclean
-Delete all files from the current directory that are created by
-configuring or building the program.  If you have unpacked the source
-and built the program without creating any other files, @samp{make
-distclean} should leave only the files that were in the distribution.
-
-@item mostlyclean
-Like @samp{clean}, but may refrain from deleting a few files that people
-normally don't want to recompile.  For example, the @samp{mostlyclean}
-target for GCC does not delete @file{libgcc.a}, because recompiling it
-is rarely necessary and takes a lot of time.
-
-@item maintainer-clean
-Delete almost everything from the current directory that can be
-reconstructed with this Makefile.  This typically includes everything
-deleted by @code{distclean}, plus more: C source files produced by
-Bison, tags tables, Info files, and so on.
-
-The reason we say ``almost everything'' is that running the command
-@samp{make maintainer-clean} should not delete @file{configure} even if
-it can be remade using a rule in the Makefile.  More generally,
-@samp{make maintainer-clean} should not delete anything that needs to
-exist in order to run @file{configure} and then begin to build the
-program.  This is the only exception; @code{maintainer-clean} should
-delete everything else that can be rebuilt.
-
-The @samp{maintainer-clean} is intended to be used by a maintainer of
-the package, not by ordinary users.  You may need special tools to
-reconstruct some of the files that @samp{make maintainer-clean} deletes.
-Since these files are normally included in the distribution, we don't
-take care to make them easy to reconstruct.  If you find you need to
-unpack the full distribution again, don't blame us.
-
-To help make users aware of this, the commands for the special 
-@code{maintainer-clean} target should start with these two:
-
-@smallexample
-@@echo "This command is intended for maintainers to use; it"
-@@echo "deletes files that may require special tools to rebuild."
-@end smallexample
-
-@item TAGS
-Update a tags table for this program.
-
-@item info
-Generate any Info files needed.  The best way to write the rules is as
-follows:
-
-@smallexample
-info: foo.info
-
-foo.info: foo.texi chap1.texi chap2.texi
-        $(MAKEINFO) $(srcdir)/foo.texi
-@end smallexample
-
-@noindent
-You must define the variable @code{MAKEINFO} in the Makefile.  It should
-run the @code{makeinfo} program, which is part of the Texinfo
-distribution.
-
-@item dvi
-Generate DVI files for all TeXinfo documentation.  
-For example:
-
-@smallexample
-dvi: foo.dvi
-
-foo.dvi: foo.texi chap1.texi chap2.texi
-        $(TEXI2DVI) $(srcdir)/foo.texi
-@end smallexample
-
-@noindent
-You must define the variable @code{TEXI2DVI} in the Makefile.  It should
-run the program @code{texi2dvi}, which is part of the Texinfo
-distribution.  Alternatively, write just the dependencies, and allow GNU
-Make to provide the command.
-
-@item dist
-Create a distribution tar file for this program.  The tar file should be
-set up so that the file names in the tar file start with a subdirectory
-name which is the name of the package it is a distribution for.  This
-name can include the version number.
-
-For example, the distribution tar file of GCC version 1.40 unpacks into
-a subdirectory named @file{gcc-1.40}.
-
-The easiest way to do this is to create a subdirectory appropriately
-named, use @code{ln} or @code{cp} to install the proper files in it, and
-then @code{tar} that subdirectory.
-
-The @code{dist} target should explicitly depend on all non-source files
-that are in the distribution, to make sure they are up to date in the
-distribution.  
-@xref{Releases, , Making Releases, standards, GNU Coding Standards}.
-
-@item check
-Perform self-tests (if any).  The user must build the program before
-running the tests, but need not install the program; you should write
-the self-tests so that they work when the program is built but not
-installed.
-@end table
-
-The following targets are suggested as conventional names, for programs
-in which they are useful.
-
-@table @code
-@item installcheck
-Perform installation tests (if any).  The user must build and install
-the program before running the tests.  You should not assume that
-@file{$(bindir)} is in the search path.  
-
-@item installdirs
-It's useful to add a target named @samp{installdirs} to create the
-directories where files are installed, and their parent directories.
-There is a script called @file{mkinstalldirs} which is convenient for
-this; find it in the Texinfo package.@c It's in /gd/gnu/lib/mkinstalldirs.
-You can use a rule like this:
-
-@comment This has been carefully formatted to look decent in the Make manual.
-@comment Please be sure not to make it extend any further to the right.--roland

-# Make sure all installation directories (e.g. $(bindir))

+@node Standard Targets
+@section Standard Targets for Users
+
+All GNU programs should have the following targets in their Makefiles:
+
+@table @samp
+@item all
+Compile the entire program.  This should be the default target.  This
+target need not rebuild any documentation files; Info files should
+normally be included in the distribution, and DVI files should be made
+only when explicitly asked for.
+
+By default, the Make rules should compile and link with @samp{-g}, so
+that executable programs have debugging symbols.  Users who don't mind
+being helpless can strip the executables later if they wish.
+
+@item install
+Compile the program and copy the executables, libraries, and so on to
+the file names where they should reside for actual use.  If there is a
+simple test to verify that a program is properly installed, this target
+should run that test.
+
+Do not strip executables when installing them.  Devil-may-care users can
+use the @code{install-strip} target to do that.
+
+If possible, write the @code{install} target rule so that it does not
+modify anything in the directory where the program was built, provided
+@samp{make all} has just been done.  This is convenient for building the
+program under one user name and installing it under another.
+
+The commands should create all the directories in which files are to be
+installed, if they don't already exist.  This includes the directories
+specified as the values of the variables @code{prefix} and
+@code{exec_prefix}, as well as all subdirectories that are needed.
+One way to do this is by means of an @code{installdirs} target
+as described below.
+
+Use @samp{-} before any command for installing a man page, so that
+@code{make} will ignore any errors.  This is in case there are systems
+that don't have the Unix man page documentation system installed.
+
+The way to install Info files is to copy them into @file{$(infodir)}
+with @code{$(INSTALL_DATA)} (@pxref{Command Variables}), and then run
+the @code{install-info} program if it is present.  @code{install-info}
+is a program that edits the Info @file{dir} file to add or update the
+menu entry for the given Info file; it is part of the Texinfo package.
+Here is a sample rule to install an Info file:
+
+@comment This example has been carefully formatted for the Make manual.
+@comment Please do not reformat it without talking to roland@gnu.ai.mit.edu.
+@smallexample
+$(infodir)/foo.info: foo.info
+# There may be a newer info file in . than in srcdir.
+        -if test -f foo.info; then d=.; \
+         else d=$(srcdir); fi; \
+        $(INSTALL_DATA) $$d/foo.info $@@; \
+# Run install-info only if it exists.
+# Use `if' instead of just prepending `-' to the
+# line so we notice real errors from install-info.
+# We use `$(SHELL) -c' because some shells do not
+# fail gracefully when there is an unknown command.
+        if $(SHELL) -c 'install-info --version' \
+           >/dev/null 2>&1; then \
+          install-info --dir-file=$(infodir)/dir $(infodir)/foo.info; \
+        else true; fi
+@end smallexample
+
+@item uninstall
+Delete all the installed files that the @samp{install} target would
+create (but not the noninstalled files such as @samp{make all} would
+create).
+
+This rule should not modify the directories where compilation is done,
+only the directories where files are installed.
+
+@item install-strip
+Like @code{install}, but strip the executable files while installing
+them.  The definition of this target can be very simple:
+
+@example
+install-strip:
+        $(MAKE) INSTALL_PROGRAM='$(INSTALL_PROGRAM) -s' install
+@end example
+
+Normally we do not recommend stripping an executable unless you are sure
+the program has no bugs.  However, it can be reasonable to install a
+stripped executable for actual execution while saving the unstripped
+executable elsewhere in case there is a bug.
+
+@comment The gratuitous blank line here is to make the table look better
+@comment in the printed Make manual.  Please leave it in.
+@item clean
+
+Delete all files from the current directory that are normally created by
+building the program.  Don't delete the files that record the
+configuration.  Also preserve files that could be made by building, but
+normally aren't because the distribution comes with them.
+
+Delete @file{.dvi} files here if they are not part of the distribution.
+
+@item distclean
+Delete all files from the current directory that are created by
+configuring or building the program.  If you have unpacked the source
+and built the program without creating any other files, @samp{make
+distclean} should leave only the files that were in the distribution.
+
+@item mostlyclean
+Like @samp{clean}, but may refrain from deleting a few files that people
+normally don't want to recompile.  For example, the @samp{mostlyclean}
+target for GCC does not delete @file{libgcc.a}, because recompiling it
+is rarely necessary and takes a lot of time.
+
+@item maintainer-clean
+Delete almost everything from the current directory that can be
+reconstructed with this Makefile.  This typically includes everything
+deleted by @code{distclean}, plus more: C source files produced by
+Bison, tags tables, Info files, and so on.
+
+The reason we say ``almost everything'' is that running the command
+@samp{make maintainer-clean} should not delete @file{configure} even if
+@file{configure} can be remade using a rule in the Makefile.  More generally,
+@samp{make maintainer-clean} should not delete anything that needs to
+exist in order to run @file{configure} and then begin to build the
+program.  This is the only exception; @code{maintainer-clean} should
+delete everything else that can be rebuilt.
+
+The @samp{maintainer-clean} target is intended to be used by a maintainer of
+the package, not by ordinary users.  You may need special tools to
+reconstruct some of the files that @samp{make maintainer-clean} deletes.
+Since these files are normally included in the distribution, we don't
+take care to make them easy to reconstruct.  If you find you need to
+unpack the full distribution again, don't blame us.
+
+To help make users aware of this, the commands for the special
+@code{maintainer-clean} target should start with these two:
+
+@smallexample
+@@echo "This command is intended for maintainers to use; it"
+@@echo "deletes files that may require special tools to rebuild."
+@end smallexample
+
+@item TAGS
+Update a tags table for this program.
+@c ADR: how?
+
+@item info
+Generate any Info files needed.  The best way to write the rules is as
+follows:
+
+@smallexample
+info: foo.info
+
+foo.info: foo.texi chap1.texi chap2.texi
+        $(MAKEINFO) $(srcdir)/foo.texi
+@end smallexample
+
+@noindent
+You must define the variable @code{MAKEINFO} in the Makefile.  It should
+run the @code{makeinfo} program, which is part of the Texinfo
+distribution.
+
+@item dvi
+Generate DVI files for all Texinfo documentation.  
+For example:
+
+@smallexample
+dvi: foo.dvi
+
+foo.dvi: foo.texi chap1.texi chap2.texi
+        $(TEXI2DVI) $(srcdir)/foo.texi
+@end smallexample
+
+@noindent
+You must define the variable @code{TEXI2DVI} in the Makefile.  It should
+run the program @code{texi2dvi}, which is part of the Texinfo
+distribution.@footnote{@code{texi2dvi} uses @TeX{} to do the real work
+of formatting. @TeX{} is not distributed with Texinfo.}  Alternatively,
+write just the dependencies, and allow GNU Make to provide the command.
+
+@item dist
+Create a distribution tar file for this program.  The tar file should be
+set up so that the file names in the tar file start with a subdirectory
+name which is the name of the package it is a distribution for.  This
+name can include the version number.
+
+For example, the distribution tar file of GCC version 1.40 unpacks into
+a subdirectory named @file{gcc-1.40}.
+
+The easiest way to do this is to create a subdirectory appropriately
+named, use @code{ln} or @code{cp} to install the proper files in it, and
+then @code{tar} that subdirectory.
+
+Compress the tar file file with @code{gzip}.  For example, the actual
+distribution file for GCC version 1.40 is called @file{gcc-1.40.tar.gz}.
+
+The @code{dist} target should explicitly depend on all non-source files
+that are in the distribution, to make sure they are up to date in the
+distribution.  
+@ifset CODESTD
+@xref{Releases, , Making Releases}.
+@end ifset
+@ifclear CODESTD
+@xref{Releases, , Making Releases, standards, GNU Coding Standards}.
+@end ifclear
+
+@item check
+Perform self-tests (if any).  The user must build the program before
+running the tests, but need not install the program; you should write
+the self-tests so that they work when the program is built but not
+installed.
+@end table
+
+The following targets are suggested as conventional names, for programs
+in which they are useful.
+
+@table @code
+@item installcheck
+Perform installation tests (if any).  The user must build and install
+the program before running the tests.  You should not assume that
+@file{$(bindir)} is in the search path.  
+
+@item installdirs
+It's useful to add a target named @samp{installdirs} to create the
+directories where files are installed, and their parent directories.
+There is a script called @file{mkinstalldirs} which is convenient for
+this; you can find it in the Texinfo package.
+@c It's in /gd/gnu/lib/mkinstalldirs.
+You can use a rule like this:
+
+@comment This has been carefully formatted to look decent in the Make manual.
+@comment Please be sure not to make it extend any further to the right.--roland
+@smallexample
+# Make sure all installation directories (e.g. $(bindir))
+# actually exist by making them if necessary.
+installdirs: mkinstalldirs
+        $(srcdir)/mkinstalldirs $(bindir) $(datadir) \
+                                $(libdir) $(infodir) \
+                                $(mandir)
+@end smallexample
+
+This rule should not modify the directories where compilation is done.
+It should do nothing but create installation directories.
