Bug description

The command

ocamlopt -a -o foo.cmxa

works on Linux, but gives an error message from "ar" on MacOSX because Darwin's "ar" command does not allow adding zero files to an archive (stupid MacOSX).

Additional information

One way to create an empty archive is:

ar rc foo.a /dev/null
ar d foo.a null

but it really hurts my sensibility to have to hack around such a problem. Does anybody have a more elegant solution?

I think I'll report this to Apple as an "ar" bug.
