I think we should be setting WINVER and _WIN32_WINNT to
_WIN32_WINNT_WS03 (0x0502) in WindowsSupport.h. We currently set it to
0x0501, and it sounds like we want to update it. I don't think that
requiring Win XP SP 2 will be that problematic in practice, but we
should be aware that we would be changing the minimum required version
of Windows (slightly).
