405# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
406#
407# Of course, Automake must honor this variable whenever it calls a
408# tool from the auxiliary directory.  The problem is that $srcdir (and
409# therefore $ac_aux_dir as well) can be either absolute or relative,
410# depending on how configure is run.  This is pretty annoying, since
411# it makes $ac_aux_dir quite unusable in subdirectories: in the top
412# source directory, any form will work fine, but in subdirectories a
413# relative path needs to be adjusted first.
414#
415# $ac_aux_dir/missing
416#    fails when called from a subdirectory if $ac_aux_dir is relative
417# $top_srcdir/$ac_aux_dir/missing
418#    fails if $ac_aux_dir is absolute,
419#    fails when called from a subdirectory in a VPATH build with
420#          a relative $ac_aux_dir
421#
422# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
423# are both prefixed by $srcdir.  In an in-source build this is usually
424# harmless because $srcdir is '.', but things will broke when you
425# start a VPATH build or use an absolute $srcdir.
426#
427# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
428# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
429#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
430# and then we would define $MISSING as
431#   MISSING="\${SHELL} $am_aux_dir/missing"
432# This will work as long as MISSING is not called from configure, because
433# unfortunately $(top_srcdir) has no meaning in configure.
434# However there are other variables, like CC, which are often used in
435# configure, and could therefore not use this "fixed" $ac_aux_dir.
436#
437# Another solution, used here, is to always expand $ac_aux_dir to an
438# absolute PATH.  The drawback is that using absolute paths prevent a
