It's a bit annoying that our sse-2 check misses the point ! Thanks for this report.
The configure check there does AC_RUN_IFELSE. So it should fail... if it were actually doing anything. Presently the check is just a stupid almost no-op, at least it's clearly a compile-only check. I've just pushed in a less stupid sse-2 code. Would you mind checking out the tip of the gf2x repository and give it a go on your machine ? I don't have access to a non-sse2 amd64 cpu.
