OK.  Do you think this is likely to be true on all systems, or should
be implement a check?  If it might be something that would be
different for specific CPUs even if they support the same instruction
set  (i.e., not all x86 compatible hardware shows the same results)
then I think the check should be done at run time rather than at
build time.

Currently we don't do 64-bit ops because of this (Matlab doesn't have
them either) but it would be nice to have them if we can.
