341# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
342# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
343# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
344#
345# Of course, Automake must honor this variable whenever it calls a
346# tool from the auxiliary directory.  The problem is that $srcdir (and
347# therefore $ac_aux_dir as well) can be either absolute or relative,
348# depending on how configure is run.  This is pretty annoying, since
349# it makes $ac_aux_dir quite unusable in subdirectories: in the top
350# source directory, any form will work fine, but in subdirectories a
351# relative path needs to be adjusted first.
352#
353# $ac_aux_dir/missing
354#    fails when called from a subdirectory if $ac_aux_dir is relative
355# $top_srcdir/$ac_aux_dir/missing
356#    fails if $ac_aux_dir is absolute,
357#    fails when called from a subdirectory in a VPATH build with
358#          a relative $ac_aux_dir
359#
360# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
361# are both prefixed by $srcdir.  In an in-source build this is usually
362# harmless because $srcdir is `.', but things will broke when you
363# start a VPATH build or use an absolute $srcdir.
364#
365# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
366# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
367#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
368# and then we would define $MISSING as
369#   MISSING="\${SHELL} $am_aux_dir/missing"
370# This will work as long as MISSING is not called from configure, because
371# unfortunately $(top_srcdir) has no meaning in configure.
372# However there are other variables, like CC, which are often used in
373# configure, and could therefore not use this "fixed" $ac_aux_dir.
374#
375# Another solution, used here, is to always expand $ac_aux_dir to an
376# absolute PATH.  The drawback is that using absolute paths prevent a
377# configured tree to be moved without reconfiguration.
