31# This definition of AC_USE_SYSTEM_EXTENSIONS is stolen from CVS
32# Autoconf.  Perhaps we can remove this once we can assume Autoconf
33# 2.62 or later everywhere, but since CVS Autoconf mutates rapidly
34# enough in this area it's likely we'll need to redefine
35# AC_USE_SYSTEM_EXTENSIONS for quite some time.
36
37# If autoconf reports a warning
38#     warning: AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
39# or  warning: AC_RUN_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
40# the fix is
41#   1) to ensure that AC_USE_SYSTEM_EXTENSIONS is never directly invoked
42#      but always AC_REQUIREd,
43#   2) to ensure that for each occurrence of
44#        AC_REQUIRE([AC_USE_SYSTEM_EXTENSIONS])
45#      or
46#        AC_REQUIRE([gl_USE_SYSTEM_EXTENSIONS])
47#      the corresponding gnulib module description has 'extensions' among
48#      its dependencies. This will ensure that the gl_USE_SYSTEM_EXTENSIONS

246# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
247# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
248# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
249#
250# Of course, Automake must honor this variable whenever it calls a
251# tool from the auxiliary directory.  The problem is that $srcdir (and
252# therefore $ac_aux_dir as well) can be either absolute or relative,
253# depending on how configure is run.  This is pretty annoying, since
254# it makes $ac_aux_dir quite unusable in subdirectories: in the top
255# source directory, any form will work fine, but in subdirectories a
256# relative path needs to be adjusted first.
257#
258# $ac_aux_dir/missing
259#    fails when called from a subdirectory if $ac_aux_dir is relative
260# $top_srcdir/$ac_aux_dir/missing
261#    fails if $ac_aux_dir is absolute,
262#    fails when called from a subdirectory in a VPATH build with
263#          a relative $ac_aux_dir
264#
265# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
266# are both prefixed by $srcdir.  In an in-source build this is usually
267# harmless because $srcdir is '.', but things will broke when you
268# start a VPATH build or use an absolute $srcdir.
269#
270# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
271# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
272#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
273# and then we would define $MISSING as
274#   MISSING="\${SHELL} $am_aux_dir/missing"
275# This will work as long as MISSING is not called from configure, because
276# unfortunately $(top_srcdir) has no meaning in configure.
277# However there are other variables, like CC, which are often used in
278# configure, and could therefore not use this "fixed" $ac_aux_dir.
279#
280# Another solution, used here, is to always expand $ac_aux_dir to an
281# absolute PATH.  The drawback is that using absolute paths prevent a
282# configured tree to be moved without reconfiguration.
