patch for making distutils cross compile on win32

I have struggled to get Python-3.3.3 distutils to cross compile win-amd64 on 
win32. For the specific command (bdist_wininst) I am using the patch below seems 
to fix things so I can build amd64 binaries on win32. The code seems a bit 
schizophrenic about whether this is supposed to work, but without the patch it 
certainly doesn't.
