Using debian-unstable's gcc-3.2 package:

Reading specs from /usr/lib/gcc-lib/powerpc-linux/3.3.2/specs

Thread model: posix

The compiler is invoked thusly:
gcc -g -O4 -mcpu=7400 -mtune=7400 -maltivec -mabi=altivec -pipe -ffast-math
-fomit-frame-pointer -D_REENTRANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64

-c -o ppc/mpegvideo_altivec.o ppc/mpegvideo_altivec.c

The compiler gives this error:
ppc/mpegvideo_altivec.c: In function `dct_quantize_altivec':
ppc/mpegvideo_altivec.c:515: error: unrecognizable insn:
