adamc@1141: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir

adamc@1141: # harmless because $srcdir is `.', but things will broke when you
adamc@1141: # start a VPATH build or use an absolute $srcdir.
adamc@1141: #
adamc@1141: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
