SDL_GL_LoadLibrary() was returning 1, and not 0, to signify "success" on the
Quartz target...fixed this to match the documented behaviour.

Subject: [PATCH]SDL mprotect() crash fix

(I'm going to throw this patch your way at the suggestion of #SDL --
for some reason, I had some difficulty sending it to the main list
last time, and I go bonkers subscribing to send each email or
patch...)

Currently, when I run SDL applications as non-root using
SDL_VIDEODRIVER=dga, the fbdev fallback mprotect()s read/write the
proper size of mmapped /dev/fb0 (7.5MB), but on framebuffer release
mprotect()s read-only the range by the entire size of my video memory
(128MB), which causes a segfault:

#0 0x002a9a27 in ?? () from /lib/libc.so.6
#1 0x04a63eb6 in SDL_XDGAUnmapFramebuffer (screen=3D0) at XF86DGA2.c:978
#2 0x04a63efc in SDL_XDGACloseFramebuffer (dpy=3D0x9d3f008, screen=3D0)
at XF86DGA2.c:268
#3 0x04a68b57 in DGA_Available () at SDL_dgavideo.c:98
#4 0x04a53677 in SDL_VideoInit (driver_name=3D0xbfb0bfc7 "dga", flags=3D0)
at SDL_video.c:180
#5 0x04a2613f in SDL_InitSubSystem (flags=3D32) at SDL.c:74
#6 0x04a2617c in SDL_Init (flags=3D32) at SDL.c:166
#7 0x08049722 in main (argc=3D1, argv=3D0x0) at testwin.c:32

This is SDL 1.2.8 on Fedora Core 4, radeon driver for a Radeon 9250,
xorg-x11-6.8.2-37.

I've attached a one-line patch against SDL CVS that updates the size
of the framebuffer at framebuffer map time so that the mprotect() on
unmap will be the same size. I'm not sure if this is the best
approach (i.e. one might want to retain the original value), but it
does make my SDL applications work without segfaulting.

-- Best of luck, Mark Schreiber

1. Compilation produce the following error on Tru64 UNIX.
cc: Severe: SDL_x11dyn.h, line 31: Cannot find file
<X11/extensions/extutil.h> specified in #include directive. (noinclfilef)
#include <X11/extensions/extutil.h>

Because Tru64 UNIX doesn't have extutil.h, this error is caused.


2. Compilation with --enable-x11-shared=no produce the following error.
cc: Error: SDL_x11sym.h, line 115: In this statement,
"Xutf8TextListToTextProperty" is not declared. (undeclared)
SDL_X11_SYM(int,Xutf8TextListToTextProperty,(Display*,char**,int,XICCEncodingStyle,XTextProperty*))

Though it doesn't have Xutf8TextListToTextProperty,
