I'm pretty sure it has to do with the fact that I'm using the mingw32 
compiler to compile NumPy, while Pythonwin was compiled using something 

It might be related to Py_complex numbers which in Python are passed 
around as structures and my understanding is different compilers treat 
this differently. 

But, it might be something else as well.   I've been surprised in the 
past by some of the quirks of compiling on windows.

The safest thing to do is compile extensions with the same compiler used 
to compile Python (but I don't have that compiler, so I can't do it).
