Eventually I figured out that importing the globals rather than adding a function would be a better solution. I went with a __declspec(dllimport) solution, which looked OK until M?ns asked whether it'd work on static builds. It didn't.

If yes then this feature is really retarded as it causes performance loss and

Asymptotically faster algorithms should always be preferred if you have
asymptotical amounts of data
