Well....

After playing with compiler flags I got radiosity working as far as I
can tell in my OpenVMS port of the "offical" POV-Ray v3.1g and I've
tried the same for the MegaPOV port and it did help some as now I can
run a little more of the "photons" test images that I couldn't before.

I tested out radiosity in MegaPOV as best as I could and it had no
problem with the test images I tested with.

But I'm still getting crashes at the same line so I still have some
kind of floating point issues left to try to work out.
