This is the first I've heard of it, though it doesn't entirely surprise
me.  The Linux kernel instructions suggest telling AMD and Cyrix CPU's
that they're 386's in order to avoid making wrong assumptions in the
course of optimization.

For future releases, I'm just going to stick with 386 optimizations, as
it seems those are fairly safe.  I'll also make a point of strongly
suggesting to people that they download and compile POV-Ray themselves
on their own hardware (once I have a good configure script put together)
in order to get better performance than they can get with a highly
generic binary.
