I'm not sure if the gap has become smaller, but ccc still generated code
that is a lot faster than gcc-3.2.

For example, take a look at these results from SCIbench
(http://math.nist.gov/scimark2), generated on an quadruple-proc EV67
machine (running Tru64 Unix btw, not Linux):

Compaq C compiler, V6.4-014 
CFLAGS = -arch ev67 -fast -O4
