The Metrowerks compilers IMHO don't have very good code generation.
When I was at Sega, I tried to help them with their compiler because the
emitted code was so bad. It would miss trivial CSE opportunities and had
numerous other problems.
If you're going to compare compilers, you need to pick one more on par
with gcc.
