2154 # it makes $ac_aux_dir quite unusable in subdirectories: in the top

2156 # relative path needs to be adjusted first.

2167 # harmless because $srcdir is `.', but things will broke when you
2168 # start a VPATH build or use an absolute $srcdir.
2170 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
