-Call to 'initwinvideo' (first C function) looks like that:
- NEWSYM InitPreGame ; Executes before starting/continuing a game
- mov byte[pressed+1],2
- pushad
- call Start60HZ
- %ifdef __OPENGL__
- call drawscreenwin
- %endif
- call initwinvideo
-
-Note: pushad / call does not 16-byte maintain stack alignment
-and breaks i386 ABI.
-
-We apply realignment attribute to all functions noticed by users.
