2179 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
2180 # source directory, any form will work fine, but in subdirectories a
2181 # relative path needs to be adjusted first.

2192 # harmless because $srcdir is `.', but things will broke when you
2193 # start a VPATH build or use an absolute $srcdir.
2195 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
