226# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
227# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
228# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
229#
230# Of course, Automake must honor this variable whenever it calls a
231# tool from the auxiliary directory.  The problem is that $srcdir (and
232# therefore $ac_aux_dir as well) can be either absolute or relative,
233# depending on how configure is run.  This is pretty annoying, since
234# it makes $ac_aux_dir quite unusable in subdirectories: in the top
235# source directory, any form will work fine, but in subdirectories a
236# relative path needs to be adjusted first.
237#
238# $ac_aux_dir/missing
239#    fails when called from a subdirectory if $ac_aux_dir is relative
240# $top_srcdir/$ac_aux_dir/missing
241#    fails if $ac_aux_dir is absolute,
242#    fails when called from a subdirectory in a VPATH build with
243#          a relative $ac_aux_dir
244#
245# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
246# are both prefixed by $srcdir.  In an in-source build this is usually
247# harmless because $srcdir is `.', but things will broke when you
248# start a VPATH build or use an absolute $srcdir.
249#
250# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
251# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
252#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
253# and then we would define $MISSING as
254#   MISSING="\${SHELL} $am_aux_dir/missing"
255# This will work as long as MISSING is not called from configure, because
256# unfortunately $(top_srcdir) has no meaning in configure.
257# However there are other variables, like CC, which are often used in
258# configure, and could therefore not use this "fixed" $ac_aux_dir.
259#
260# Another solution, used here, is to always expand $ac_aux_dir to an
261# absolute PATH.  The drawback is that using absolute paths prevent a
262# configured tree to be moved without reconfiguration.
