[SDL] [PATCH] fix FB_VideoQuit for ia64
Jesse Barnes

I noticed that on my ia64 machine when SDL_Quit was called, the machine would
hang in weird ways. It turned out to be caused by a machine check in the
memset() call near the top of FB_VideoQuit. Generally memset shouldn't be
used on I/O regions like the framebuffer or other I/O device memory (the
Linux kernel has special routines for dealing with I/O memory), so I changed
the #ifdef __powerpc__ to #if defined(__powerpc__) || defined(__ia64__) and
SDL_Quit now works properly. The change should probably be made
unconditional though since doing one byte at a time is the only way to be
portable, afaik.
     2 To compile and install SDL:
     4     1.  Run './configure; make; make install'
     6         If you are compiling for Windows using gcc, read the FAQ at:
     9         If you are compiling using Visual C++ on Win32, you should read
    10         the file VisualC.html
    12     2.  Look at the example programs in ./test, and check out the HTML
    13         documentation in ./docs to see how to use the SDL library.
    15     3.  Join the SDL developer mailing list by sending E-mail to
    17         and put "subscribe" in the subject of the message.
    19         Or alternatively you can use the web interface:
    22 That's it!
