annotate include/SDL_error.h @ 1230:88c2d6aed428

From Mike Frysinger and/or Gentoo: - libsdl-PIC-load-mmx-masks-from-stack.patch this one may be a little controversial ... the fix here is again that you cant reference the memory addresses like this to load into a mmx register, so the way to do it is to push two 32bit words onto the stack, load the 64bit value off of the stack into the mmx register, and then adjust the stack so that it's back to normal.
