I installed python-xy 2 years ago with python 2.6 and didn't update, so my
information is not up-to-date

It looks like my MingW version uses mingw32-gcc-4.4.0.exe

for python 2.6 which came with python-xy:
        self.set_executables(compiler='gcc -mno-cygwin -O -Wall',
                             compiler_so='gcc -mno-cygwin -mdll -O -Wall',
                             compiler_cxx='g++ -mno-cygwin -O -Wall',
                             linker_exe='gcc -mno-cygwin',
                             linker_so='%s -mno-cygwin %s %s'
                                        % (self.linker_dll, shared_option,
                                           entry_point))

However, I'm running python 2.5, 2.7, 3.2 and 3.3 additionally. And they are
all python.org versions without any changes (except IDLE bugs :).
I don't have any compilation problems with any of them.

Until recently statsmodels used distutils from numpy which adds some patches
AFAIK. The current statsmodels setup.py just uses plain distutils and
setuptools. (The setup.py is largely copied from pandas which has a lot more
C extensions than statsmodels.)

numpy scipy binaries for Windows are still compiled against MingW 3.x, but
David Cournapeau is looking into upgrading to the latest MingW(-64) right now.

also (from some comments about problems a long time ago): I don't have
cygwin installed, so there is no confusion between cygwin and msys/mingw
paths possible.
