Well, time ago I compiled Povray 3.01 with gcc 2.7.2.1 and leave this
exec in the HD. When I downloaded the pgcc, I edited the makefile so
it has only the -O6 switch enabled, and compiled the same sources.

Running the old version (-M486 -funroll-loops) with the skyvase.pov
scene, it took 10 minutes 40 seconds. Running the pentium compiled
version, the same scene with the same povray settings, it took 9
minutes 30 seconds, so it makes a good job.
