819# it makes $ac_aux_dir quite unusable in subdirectories: in the top

821# relative path needs to be adjusted first.
822#

824# fails when called from a subdirectory if $ac_aux_dir is relative
825# $top_srcdir/$ac_aux_dir/missing

827# fails when called from a subdirectory in a VPATH build with
828# a relative $ac_aux_dir
829#
830# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
831# are both prefixed by $srcdir. In an in-source build this is usually
aaccad27 832# harmless because $srcdir is '.', but things will broke when you
6cc5e1a6
DB
833# start a VPATH build or use an absolute $srcdir.
834#
835# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
836# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
837# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
838# and then we would define $MISSING as
839# MISSING="\${SHELL} $am_aux_dir/missing"
840# This will work as long as MISSING is not called from configure, because

843# configure, and could therefore not use this "fixed" $ac_aux_dir.

1295
