From what I can tell my build of POV-Ray 3.1e seems to be running in
fairly good form. I checked with the benchmark times for this system
and I appear to be in the ballpark.

The only thing left to do to enhance performance a tad would be to get
this in parallel across a few systems ...
Anyone have any thoughts on my compiler flags ?
