Are you sure we should deviate from VC's behavior here? I thought the whole point of Microsoft ABI support was so we could compile a program with Clang against a DLL compiled with VC (and //vice versa//), and have it all just work. (At least, that's what I had in mind when I started all this :).
I do admit, this might be a bit nicer if we were the ones driving the ABI "spec" (inasmuch as there even //is// one to follow), but we're not. (Then again, they do only have internal linkage...)
On a related note, I now know I need to investigate VC's behavior when a mangled name refers to multiple unnamed tag types (if it's even possible...).
