 # argp-standalone
 This is a continuation of [Niels Möller](https://www.lysator.liu.se/~nisse/)'s
 work on an argp library for systems which don't provide one themselves (most
 non-GNU ones).
 After noticing issues with executables built against argp-standalone 1.3, I
 decided to fork it and continue the effort.
 This repository is the result of making a timeline with releases 1.0 to 1.3
 (obtained from [here](https://www.lysator.liu.se/~nisse/misc/)) of the original
 argp-standalone, copying files from glibc 2.33 and fixing them up for
 compatibility, and finally some general clean up. I commited many trivial
 changes from the glibc version in order to make updating easier.
 It is my expectation that this library will be useful to others. Feel free to
 open an issue or make a PR.

 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
 #
 # Of course, Automake must honor this variable whenever it calls a
 # tool from the auxiliary directory.  The problem is that $srcdir (and
 # therefore $ac_aux_dir as well) can be either absolute or relative,
 # depending on how configure is run.  This is pretty annoying, since
 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 # source directory, any form will work fine, but in subdirectories a
 # relative path needs to be adjusted first.
 #
 # $ac_aux_dir/missing
 #    fails when called from a subdirectory if $ac_aux_dir is relative
 # $top_srcdir/$ac_aux_dir/missing
 #    fails if $ac_aux_dir is absolute,
 #    fails when called from a subdirectory in a VPATH build with
 #          a relative $ac_aux_dir
 #
 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 # are both prefixed by $srcdir.  In an in-source build this is usually
 # harmless because $srcdir is `.', but things will broke when you
 # start a VPATH build or use an absolute $srcdir.
 #
 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 # and then we would define $MISSING as
 #   MISSING="\${SHELL} $am_aux_dir/missing"
 # This will work as long as MISSING is not called from configure, because
 # unfortunately $(top_srcdir) has no meaning in configure.
 # However there are other variables, like CC, which are often used in
 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 #
 # Another solution, used here, is to always expand $ac_aux_dir to an
 # absolute PATH.  The drawback is that using absolute paths prevent a
 # configured tree to be moved without reconfiguration.

 ##   (We might end up doing this anyway to support other compilers.)

 ## - Using -M directly means running the compiler twice (even worse

Érico Rolim	e5fe9ad9e8	Check for libintl header and add dgettext wrapper. The dgettext_safe wrapper is used in the few situations where it wasn't possible to immediatelly tell that the msgid parameter wasn't NULL. We can probably add some debug printing code here at some point to try and bring bugs upstream, if it makes sense. Some inspiration from https://github.com/xhebox/libuargp	2021-02-16 01:47:29 -03:00
