I might be completely wrong (I just happened to skim past this patch), but shouldn't the SSE2 code be a runtime check?  The #ifdef SSE2 is only good for knowing if you can use the intrinsics or not (if the compiler supports SSE2).  I don't know the current standing expectation of having SSE2 support is, but last I remember it wasn't considered a requirement:
