30# This definition of AC_USE_SYSTEM_EXTENSIONS is stolen from CVS
31# Autoconf.  Perhaps we can remove this once we can assume Autoconf
32# 2.62 or later everywhere, but since CVS Autoconf mutates rapidly
33# enough in this area it's likely we'll need to redefine
34# AC_USE_SYSTEM_EXTENSIONS for quite some time.

37#     warning: AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
38# or  warning: AC_RUN_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
39# the fix is
40#   1) to ensure that AC_USE_SYSTEM_EXTENSIONS is never directly invoked
41#      but always AC_REQUIREd,
42#   2) to ensure that for each occurrence of
43#        AC_REQUIRE([AC_USE_SYSTEM_EXTENSIONS])
44#      or
45#        AC_REQUIRE([gl_USE_SYSTEM_EXTENSIONS])
46#      the corresponding gnulib module description has 'extensions' among
47#      its dependencies. This will ensure that the gl_USE_SYSTEM_EXTENSIONS

185# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
186# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
187# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
188#
189# Of course, Automake must honor this variable whenever it calls a
190# tool from the auxiliary directory.  The problem is that $srcdir (and
191# therefore $ac_aux_dir as well) can be either absolute or relative,
192# depending on how configure is run.  This is pretty annoying, since
193# it makes $ac_aux_dir quite unusable in subdirectories: in the top
194# source directory, any form will work fine, but in subdirectories a
195# relative path needs to be adjusted first.
196#
197# $ac_aux_dir/missing
198#    fails when called from a subdirectory if $ac_aux_dir is relative
199# $top_srcdir/$ac_aux_dir/missing
200#    fails if $ac_aux_dir is absolute,
201#    fails when called from a subdirectory in a VPATH build with
202#          a relative $ac_aux_dir
203#
204# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
205# are both prefixed by $srcdir.  In an in-source build this is usually
206# harmless because $srcdir is `.', but things will broke when you
207# start a VPATH build or use an absolute $srcdir.
208#
209# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
210# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
211#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
212# and then we would define $MISSING as
213#   MISSING="\${SHELL} $am_aux_dir/missing"
214# This will work as long as MISSING is not called from configure, because
215# unfortunately $(top_srcdir) has no meaning in configure.
216# However there are other variables, like CC, which are often used in
217# configure, and could therefore not use this "fixed" $ac_aux_dir.
218#
219# Another solution, used here, is to always expand $ac_aux_dir to an
220# absolute PATH.  The drawback is that using absolute paths prevent a
221# configured tree to be moved without reconfiguration.
