Thanks, appreciated!

Although it does look like you did get my two bounced mails (with the
-l/-L and -M* stuff included), -M, -MM, etc (they do not take arguments
like the other -M?) and --version, -dump* and -print* do not work (-M*
is used by some newer autotools stuff, as well as --version, and here
and there something uses -dump*/print*).

This is sorda what I need, although in no way the best solution :)
