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