As I said, I've tried the obvious things & they didn't make any

OK. Looks like I was mistaken. Strictness annotations *do* make a
difference! Humph. Wonder what I was doing wrong yesterday?
Anyway timings follow, with all strict datatypes in the Haskell
version:
Langauge File Time in seconds
Haskell ray.hs 38.2
OCaml ray.ml 23.8
g++-4.1 ray.cpp 12.6
(ML & C++ Code from
http://www.ffconsultancy.com/languages/ray_tracer/comparison.html)
Gcc seems to have got quite a bit better since Jon last benchmarked
this code.
