Subject: [SDL] Opteron MMX patches for SDL_blit.c and SDL_blit_A.c
The inline MMX assembly in SDL_blit.c and SDL_blit_A.c compiles and runs fine
unmodified under AMD Opteron. The inline assembly in SDL_yuv_mmx.c and
SDL_blit_N.c unfortunately isn't directly compatible.
I've included diffs from SDL_blit.c and SDL_blit_A.c that allow the MMX
assembly to be compiled when USE_ASMBLIT, __x86_64__, and __GNUC__ are all
defined. All I had to modify was typedefs, the inline assembly itself wasn't
touched.
