Should one expect minor numerical differences between 64bit and 32bit R on
Windows? Hunting around the lists I've not been able to find a definitive
answer yet. Seems plausible using different precision arithmetic, but waned
to confirm from those who might know for sure.

A more important difference is the number of registers available on
the CPU, which differs between i386 and x86_64. Hence computations
get done in different orders by optimizing compilers.
And yes, all x86_64 CPUs have SSE, so the optimizer uses them at the
compiler settings we use.

Hi
Just committed another fix that solves this problem for me at least. If
you want to test for yourself, the magic revision number that you are
looking for is r54330.
Thanks again for your help.
