Oh right - so gcc supports you building against msvcr71.dll which VC8 
specifically prevents.

Fair enough, I wasn't aware of this. I *have* heard reports of problems 
for certain projects caused by extensions built with gcc on windows, but 
they seemed like corner cases. (One was a database project which passed 
file handles to the CRT - or something like that - IIRC.)
