sysdep: remove round; document several functions; use ia32.h header instead of a hack that extern-declared sysdep functions that are implemented as macro-redirection wsdl: add SDL_EnableKeyRepeat stub; group related functions in header together; no longer need OS_WIN wrapper around that This was SVN commit r3115.
