I should qualify this. I would build Windows builds that use the -msse2 flag
but still do auto detection.

The class of CPU's that will fail are mainly the Pentium (and AMD) MMX. The
auto detect (which only checks for SSE not SSE2) will detect SSE on MMX
systems and then fail with an illegal operation.

I guess for completeness one might consider building a non-sse build for
those system.
