241# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
242# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
243# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
244#
245# Of course, Automake must honor this variable whenever it calls a
246# tool from the auxiliary directory.  The problem is that $srcdir (and
247# therefore $ac_aux_dir as well) can be either absolute or relative,
248# depending on how configure is run.  This is pretty annoying, since
249# it makes $ac_aux_dir quite unusable in subdirectories: in the top
250# source directory, any form will work fine, but in subdirectories a
251# relative path needs to be adjusted first.
252#
253# $ac_aux_dir/missing
254#    fails when called from a subdirectory if $ac_aux_dir is relative
255# $top_srcdir/$ac_aux_dir/missing
256#    fails if $ac_aux_dir is absolute,
257#    fails when called from a subdirectory in a VPATH build with
258#          a relative $ac_aux_dir
259#
260# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
261# are both prefixed by $srcdir.  In an in-source build this is usually
262# harmless because $srcdir is '.', but things will broke when you
263# start a VPATH build or use an absolute $srcdir.
264#
265# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
266# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
267#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
268# and then we would define $MISSING as
269#   MISSING="\${SHELL} $am_aux_dir/missing"
270# This will work as long as MISSING is not called from configure, because
271# unfortunately $(top_srcdir) has no meaning in configure.
272# However there are other variables, like CC, which are often used in
273# configure, and could therefore not use this "fixed" $ac_aux_dir.
274#
275# Another solution, used here, is to always expand $ac_aux_dir to an
276# absolute PATH.  The drawback is that using absolute paths prevent a
277# configured tree to be moved without reconfiguration.
