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