348# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

350# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
351#
352# Of course, Automake must honor this variable whenever it calls a
353# tool from the auxiliary directory.  The problem is that $srcdir (and
354# therefore $ac_aux_dir as well) can be either absolute or relative,
355# depending on how configure is run.  This is pretty annoying, since
356# it makes $ac_aux_dir quite unusable in subdirectories: in the top
357# source directory, any form will work fine, but in subdirectories a
358# relative path needs to be adjusted first.
359#
360# $ac_aux_dir/missing
361#    fails when called from a subdirectory if $ac_aux_dir is relative
362# $top_srcdir/$ac_aux_dir/missing
363#    fails if $ac_aux_dir is absolute,
364#    fails when called from a subdirectory in a VPATH build with
365#          a relative $ac_aux_dir
366#
367# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
368# are both prefixed by $srcdir.  In an in-source build this is usually
369# harmless because $srcdir is `.', but things will broke when you
370# start a VPATH build or use an absolute $srcdir.
371#
372# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
373# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
374#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
375# and then we would define $MISSING as
376#   MISSING="\${SHELL} $am_aux_dir/missing"
377# This will work as long as MISSING is not called from configure, because
378# unfortunately $(top_srcdir) has no meaning in configure.
379# However there are other variables, like CC, which are often used in
380# configure, and could therefore not use this "fixed" $ac_aux_dir.
381#
382# Another solution, used here, is to always expand $ac_aux_dir to an
383# absolute PATH.  The drawback is that using absolute paths prevent a
