2264 # it makes $ac_aux_dir quite unusable in subdirectories: in the top

2266 # relative path needs to be adjusted first.

2275 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
2276 # are both prefixed by $srcdir. In an in-source build this is usually
2277 # harmless because $srcdir is `.', but things will broke when you
2278 # start a VPATH build or use an absolute $srcdir.
2280 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
