Fixed bug #878
Jack Jansen 2009-11-05 14:20:22 PST
I'm building "fat" SDL 1.3 libraries for MacOSX, but now I am running into the
issue that audio does not work on PowerPC macintoshes if you build the library
on an Intel.
The problem is that configure hard-codes the byteorder, which is then stored in
SDL_config.h
