c3d8674a26
version of patch 1448395 by Aubin and some of my own changes. Notably: * Two elements of a struct in backends/midi/quicktime.cpp needed to be forced to BE. * NASM set to build Mach-O binaries * configure now checks for Altivec support on Darwin hosts, instead of assuming it. Altivec support can also be disabled (not 100% sure if t his is actually needed, but might be handy for crosscompiling). * The aliasing of the symbols contained in the .asm files done on Windows were also needed on MacOS. Note that while the asm code is properly compiled and linked in, HQ2/3x support will still not work properly on Intel macs if NASM is enabled. svn-id: r21280
