Date: Mon, 28 Jun 2004 19:58:08 +0900 From: Hayashi Naoyuki Subject: SDL_types.h - fix for Tru64 MME The following two problems are fixed. 1. Type of Uint64 is "long long" in SDL_types.h, but is "long" in mmbasic.h(Tru64 UNIX MME header file). 2. Uint8, Uint16 and Uint32 are redefined if you compile a file including mmbasic.h and SDL_types.h.
