This is educational for me; to minimize pain, I settled on visual studio +
intel compiler long ago whenever I am coerced into windows development.

You mentioned that did some surfing; did you encounter this page
<http://www.secker.nl/2012/03/08/setup-python-2-7-2-and-mingw-on-windows-xp/>?
Apparently, mingw should be able to link against the standard, visual
studio compiled python lib.  Which would be a blessing for you if it
works... Are you trying to build 32-bit binaries linked against 64-bit
python libs by any chance?

If you don't get any joy, I'll try setting up an official python binaries +
mingw environment on my windwoes system at home after work today or
tomorrow.  Are you strictly targeting 2.7?
