Fixed a few issues compiling with Mac OS X 10.6
Unfortunately the audio and cdrom systems do not build at all, and if you
disable those, SDL still fails to link with these errors:

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
