Subject: [SDL] SDL and gcc >= 3.3.1 fix
Lately, I upgraded my gcc compiler and could trigger the error described
in this thread :
http://www.libsdl.org/pipermail/sdl/2003-September/056163.html
SDL_RLEaccel.c: In function `RLEClipBlit':
SDL_RLEaccel.c:845: error: invalid `asm': invalid expression as operand
SDL_RLEaccel.c:845: error: invalid `asm': invalid expression as operand
SDL_RLEaccel.c:845: error: invalid `asm': invalid expression as operand
The attached patch fixes this issue, and is smaller than the previous
one, as I was able to trigger the issue, so I could narrow it.
