After further investigation, it looks like gnubg does runtime probing, but
if you tell it to use SSE, it also

yes, since Venice Stepping E3 and San Diego Stepping E4.
But thanks for the reminder, there were indeed CPUs before that.

Are there amd64 machines which do *not* support sse3?

If it probes, it is most likely loading an optimized asm module, and you
dont need the SSE switch at all.

http://en.wikipedia.org/wiki/X86-64 says
gnubg supports optionally building with SSE support for increased speed in
the analytical engine. I have to date kept this disabled to not generate
binaries that might not run on all otherwise-supported Debian systems.
However, a user mentioned that he thinks all chips that fall into the
