250# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
251#
252# Of course, Automake must honor this variable whenever it calls a
253# tool from the auxiliary directory.  The problem is that $srcdir (and
254# therefore $ac_aux_dir as well) can be either absolute or relative,
255# depending on how configure is run.  This is pretty annoying, since
256# it makes $ac_aux_dir quite unusable in subdirectories: in the top
257# source directory, any form will work fine, but in subdirectories a
258# relative path needs to be adjusted first.
259#
260# $ac_aux_dir/missing
261#    fails when called from a subdirectory if $ac_aux_dir is relative
262# $top_srcdir/$ac_aux_dir/missing
263#    fails if $ac_aux_dir is absolute,
264#    fails when called from a subdirectory in a VPATH build with
265#          a relative $ac_aux_dir
266#
267# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
268# are both prefixed by $srcdir.  In an in-source build this is usually
269# harmless because $srcdir is `.', but things will broke when you
270# start a VPATH build or use an absolute $srcdir.
271#
272# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
273# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
274#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
275# and then we would define $MISSING as
276#   MISSING="\${SHELL} $am_aux_dir/missing"
277# This will work as long as MISSING is not called from configure, because
278# unfortunately $(top_srcdir) has no meaning in configure.
279# However there are other variables, like CC, which are often used in
280# configure, and could therefore not use this "fixed" $ac_aux_dir.
281#
282# Another solution, used here, is to always expand $ac_aux_dir to an
