That is what I thought he meant as well, and it seems to be a widespread 
belief. The fact that numpy is built with mingw proves it wrong, 
obviously. I just wanted to point out what the real limitation is: don't 
mix and blend CRTs and CRT resources. This is obviously not a Windows or 
Python specific problem.

I use this 32 bit mingw binary to build my Cython and f2py extensions. I 
works like a charm. I have licenses for Intel compilers at work, but I 
prefer gfortran 4.4.
