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.
