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.

The rectangles must all be confined within the screen boundaries (no clipping is done)\&. .PP This function should not be called while \fBscreen\fR is \fIlocked\fR\&. .PP .RS \fBNote: .PP It is adviced to call this function only once per frame, since each call has some processing overhead\&. This is no restriction since you can pass any number of rectangles each time\&. .PP The rectangles are not automatically merged or checked for overlap\&. In general, the programmer can use his knowledge about his particular rectangles to merge them in an efficient way, to avoid overdraw\&. .RE .SH "SEE ALSO" .PP \fI\fBSDL_UpdateRect\fP\fR, \fI\fBSDL_Rect\fR\fR, \fI\fBSDL_Surface\fR\fR, \fI\fBSDL_LockSurface\fP\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 23:01
