If *that* is a/the change we need to make for build systems to "support
modules", that is *laughably* trivial compared to "the Fortran way".

That said, you're assuming that clang doesn't mention the modulemap as a
required include file... because I think that would be sufficient, and
wouldn't be surprised if that *is* already happening.
