I use the stock gcc in the developer tools, provided by Apple. I don't 
use -faltivec since it enables Altivec code if you use it but do not 
generate Altivec code from regular code (as of gcc 3.3).

% gcc --version

My CFLAGS for compiling qemu are :
CFLAGS=-Wall -O2 -fkeep-inline-functions -finline-functions 
-fno-strict-aliasing -mpowerpc-gpopt -mpowerpc-gfxopt -mcpu=7400

but it seems that only the -mcpu=7400 makes a difference. It may be 
that gcc 3.4.1 optimizes better.

I don't have much time for testing right now (on vacation next week and 
lots to do before that), but I'll do it if I find some time.

Lga.
