What happens if you try to build a windows installer "python setup.py
bdist_wininst"

Also, have you attempted to specify the compiler in
"$PYTHON_ROOT\Lib\distutils\distutils.cfg" ?

I've got a script I use to manually change the "build" section of this file
between

[build]
msvc

and

[build]
mingw32

to switch between default compilers when I've had issues with setup.py.
