Performance results for the above expressions, using N=100000:
            Unfused Fused Chunky
T3E/KCC 27.4 43.2 34.0 (mcurie.nersc.gov)
alpha/DECcxx 8.7 12.7 11.9 (hgar1.cwru.edu)
alpha/KCC 8.7 12.6 12.2 (hgar1.cwru.edu)
i686/egcs 14.4 10.4 19.0 (n2001.lbl.gov)
O2000/KCC 14.4 22.3 18.4 (bluemountain.acl.lanl.gov)

It improves the performance of "chunky" somewhat. The
test code for chunky is written in C-style; KCC usually makes
the biggest difference when you have lots of C++ stuff
(especially lightweight classes e.g. complex<>).

Cheers,
Todd
