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