probably by contrib/buildsystems/generate, but I don't quite remember ;)

Anyway, if the result of contrib/buildsystems/generate builds differently than "make MSVC=1", then I consider this an issue with contrib/buildsystems/generate, not the MSVC-port.

I can try to reproduce it at some point, but I'm really tight on time right now.
