RtlGetVersion is the correct way to get the Windows version now. Note: ntdll does not need to be manually loaded into the runtime, as this is the one special library that is automatically loaded upon launch. Signed-off-by: Seija Kijin --- mingw: prefer RtlGetVersion over GetVersion GetVersion has its behavior changed in Windows 8 and above anyway, so this is the right way to do it now.
