331# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
332# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
333# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
334#
335# Of course, Automake must honor this variable whenever it calls a
336# tool from the auxiliary directory.  The problem is that $srcdir (and
337# therefore $ac_aux_dir as well) can be either absolute or relative,
338# depending on how configure is run.  This is pretty annoying, since
339# it makes $ac_aux_dir quite unusable in subdirectories: in the top
340# source directory, any form will work fine, but in subdirectories a
341# relative path needs to be adjusted first.
342#
343# $ac_aux_dir/missing
344#    fails when called from a subdirectory if $ac_aux_dir is relative
345# $top_srcdir/$ac_aux_dir/missing
346#    fails if $ac_aux_dir is absolute,
347#    fails when called from a subdirectory in a VPATH build with
348#          a relative $ac_aux_dir
349#
350# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
351# are both prefixed by $srcdir.  In an in-source build this is usually
352# harmless because $srcdir is '.', but things will broke when you
353# start a VPATH build or use an absolute $srcdir.
354#
355# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
356# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
357#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
358# and then we would define $MISSING as
359#   MISSING="\${SHELL} $am_aux_dir/missing"
360# This will work as long as MISSING is not called from configure, because
361# unfortunately $(top_srcdir) has no meaning in configure.
362# However there are other variables, like CC, which are often used in
363# configure, and could therefore not use this "fixed" $ac_aux_dir.
364#
365# Another solution, used here, is to always expand $ac_aux_dir to an
366# absolute PATH.  The drawback is that using absolute paths prevent a
367# configured tree to be moved without reconfiguration.
