One potential problem I just discovered is dependency on a DLL called 
libpthreadGC2.dll. First, it's a DLL that must be put somewhere. And 
second it is LGPL, but mingw uses it for any OpenMP by default. Well it 
is compiled independently so it should not taint the rest of NumPy, but 
it would be there. It would be better to have a different BSD pthreads 
library to link with instead, but I don't know of any that could be used.
