The standard makefile for PoV does not optimise for any particular
version of
the x86 so adding a -mpentiumpro might be a good thing to do, it might
add some
extra speed due to the specification to (e)gcc that it's safe to do some
things,
that "normal" pentiums doesn't understand.
note, I haven't done this myself, but it should be safe, since we are
using -O6.
