Partial support for cross-platform generation of bdist_wininst .exe's.

Unfortunately, bdist_wininst doesn't fix up #! lines, so python.exe or 
pythonw.exe have to be on PATH for generated scripts to work.  This 
could probably be fixed up with a post-install script, but that's a 
job for another day.
