Definitely. On Windows it is relatively common to configure distutils to 
compile extensions with Mingw, which is likely to have problems with 
FILE* from the Microsoft C runtime [1].


[1] I say *likely* because I have vague memories of Mingw being able to 
compile against msvcrt, but I'm not sure about this. This is actually 
less of an issue at the moment as we are now using a Microsoft compiler 
for which a free version is available. This wasn't the case for a while 
(and still isn't for those using Python 2.5 and earlier).
