I've changed the implementation. It's now public domain code from PDCLib.

     https://hg.libsdl.org/SDL/rev/19998f9082dc

We have no intention of shipping another release of SDL 1.2, but on 1.2, 
SDL_qsort is #defined to qsort in the headers if HAVE_QSORT is set by 
the configure script...that is to say, if Debian wants to replace 
SDL_qsort.c with an empty file for its SDL 1.2 package, it will likely 
build the exact same binary.

Let me know if you have any other concerns.

Thanks,
--ryan.
