Huh. I was under the impression that the module map "link" declaration was applied. Is that not the case? Should it be? Should I file a bug?

I seem to be making headway, though this means my Swift target becomes even more problematic for dependent projects to use (with a rapidly growing Makefile).

Ah, much nicer. Thanks for the tip!
