	And from the english man page:

sse,387
   Attempt to utilize both instruction sets at once.  This effec-
   tively double the amount of available registers and on chips
   with separate execution units for 387 and SSE the execution
   resources too.  Use this option with care, as it is still
   experimental, because the gcc register allocator does not model
   separate functional units well.

	:-)

	BTW, I realized that my statement about povray not being able
to use SSE/SSE2/similar instructions seems plain wrong, as I thought
those were (still) limited to single-precision arithmetics.
	My bad.
	So it's seems they could be actually quite valuable, and
I will consider them in the new configure script for 3.6.  Thanks
for pointing this out.

	- NC
