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
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?
