	Note that the -ffast-math and -m3dnow options are not part of
the official povray-3.6.1 configure script, but were most likely added
by the gentoo folks.  The former will be in official 3.6.2 - it was not
included so far, but indeed works without problem.  The latter has no
effect at all (identical binaries with and without the option on AMD
K7/K8 platforms) and is therefore useless; same for -mmmx.
