[PyMOL] Building pymol on Windows?

Since building under Mingw is turning out to be nontrivial, let me
broaden the question slightly.  How does one build PyMol from 
source (via subversion) on Windows?  The goal is to produce a 
Pymol that uses native Windows graphics, not one that requires X11.

Other than Warren, has anybody successfully built PyMol on Windows?
If so, please let us know how it was done.

Thanks,

David Mathog
