I did a little test by comparing both performace of both compiler using
spice3E2.  The flags are cc -O and gcc -O2.  I tested using a few circuits
and the results shown that gcc is 5 percent faster then bundled cc on the
average.  Previously, I did the same test using gcc1.40 and it was 5 percent
slower.  I tried with other optimisation parameters like using -O3 and
-O2 -funroll-loop but both shown to be worst than -O2 for gcc2.0.
I'm not too sure how it fair against the -O4 flag in cc or the unbundled
sun C 1.0.
