I don't want people to get the wrong impression: Win32 *IS* a fully  
supported platform. Our support could be better than it is, but fixing  
win32 bugs in the existing code is just as much of a priority as any other  
platform. Commits that breaks tests on win32 are reverted almost  
immediately. The only issue is that there are simply fewer developers who  
have the desire, expertise, or dev evironments to work on Windows.
