Huh. Just curious, this "regular" gcc 3.3, is it from FSF or is it a
Darwin-version? Do you use "-faltivec" or "-maltivec -mabi=altivec" to
add altivec support? The latter is FSF.

This is what I use right now (FSF):

address@hidden damm $ gcc --version
gcc (GCC) 3.4.1 20040803 (Gentoo Linux 3.4.1-r3, ssp-3.4-2, pie-8.7.6.5)
