annotate include/SDL_stdinc.h @ 3950:9d9e15ab1697 SDL-1.2
Check if yasm supports a nasm-specific syntax we use (it doesn't in 0.5.0,
which is still common in Linux distros, and does in 0.6.0). Disable it if we
don't, attempting to fallback to using nasm. Thanks to Mike Frysinger for the
patch.
Fixes Bugzilla #393.
