I could test on gcc63 (
Linux deluxe 2.6.26-2-sparc64-smp #1 SMP Thu Jan 27 03:27:39 UTC 2011 sparc64 GNU/Linux
) and mandelbrot and cellauto failed. I left them out and pushed the rest.

Cellauto could probably be made bitexact with not much effort.

On gcc42 (
Linux gcc42 2.6.27.1 #476 Tue Oct 20 14:25:23 CST 2009 mips64 GNU/Linux
gcc (RAYS 4.3.0-4.rays0) 4.3.1 20080501 (prerelease)
), compilation fails with:

make: *** [libavformat/asfcrypt.o] Error 1

I can make further tests if someone happens to be interested, but maybe this
is just gcc being too old.
