We can't really do it the way midl does. midl can import files from
system directories and from resource of dlls. In UNIX we don't have such
dirs. We can add support for tlb libs in PE files, but I don't think we
want to do it for Wine's builtin dlls. I thought that we could add an
other, more UNIX like, option that will be a nice workaround. Of course
-I also does the trick although IMO it's better to have -L option. I'll
send a patch that uses include search patch so you can decide which one
to use.

Thanks,
