333# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
334# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
335# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
336#
337# Of course, Automake must honor this variable whenever it calls a
338# tool from the auxiliary directory. The problem is that $srcdir (and
339# therefore $ac_aux_dir as well) can be either absolute or relative,
340# depending on how configure is run. This is pretty annoying, since
341# it makes $ac_aux_dir quite unusable in subdirectories: in the top
342# source directory, any form will work fine, but in subdirectories a
343# relative path needs to be adjusted first.
344#
345# $ac_aux_dir/missing
346# fails when called from a subdirectory if $ac_aux_dir is relative
347# $top_srcdir/$ac_aux_dir/missing
348# fails if $ac_aux_dir is absolute,
349# fails when called from a subdirectory in a VPATH build with
350# a relative $ac_aux_dir
351#
352# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
353# are both prefixed by $srcdir. In an in-source build this is usually
354# harmless because $srcdir is `.', but things will broke when you
355# start a VPATH build or use an absolute $srcdir.
356#
357# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
358# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
359# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
360# and then we would define $MISSING as
361# MISSING="\${SHELL} $am_aux_dir/missing"
362# This will work as long as MISSING is not called from configure, because
363# unfortunately $(top_srcdir) has no meaning in configure.
364# However there are other variables, like CC, which are often used in
365# configure, and could therefore not use this "fixed" $ac_aux_dir.
366#
367# Another solution, used here, is to always expand $ac_aux_dir to an
368# absolute PATH. The drawback is that using absolute paths prevent a
