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

430 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
431 # are both prefixed by $srcdir. In an in-source build this is usually
432 # harmless because $srcdir is '.', but things will broke when you
433 # start a VPATH build or use an absolute $srcdir.
