Date: Fri, 31 Dec 2004 04:14:09 +0900 From: Hayashi Naoyuki Subject: SDL patch for Tru64 UNIX 4.0X SDL-1.2.8 support only Tru64 5.X. This patch is for Tru64 UNIX 4.X.(tested on Tru64 UNIX 4.0G and 5.1B) SDL-1.2.8/configure.in: ld doesn't accept -pthread option. cc -pthread has same effect as -D_REENTRANT when compiling, and has same effect as -lpthread -lexc when linking. SDL-1.2.8/include/begin_code.h: Old Compaq C Compiler accept not inline but __inline. SDL-1.2.8/src/audio/SDL_mixer_MMX.c: SDL-1.2.8/src/audio/SDL_mixer_MMX.h: Old Compaq C Compiler doesn't accept //. SDL-1.2.8/src/cdrom/osf/SDL_syscdrom.c: When becoming Tru64 v5.0 from Tru64 v4.0, the arrangement of the cd-rom device was changed.
