pythonxy, and I guess the others, only have MingW for 32 bit, it
includes gfortran which is still incompatible with scipy.

(Skipper is building the statsmodels binaries with Microsoft compilers.
a quick check:
sklearn binaries for 64bit windows point to Gohlke which "Requires
Numpy-MKL" not stock numpy.
pymc (requires fortran) is 32 bit binaries only
)

I don't see anything for 64 bit windows outside of Microsoft and Intel
compilers, and binary distributions that use those.
