Okay, it breaks the build when you do --disable-sse3.  I see that too.

It is okay to fix that any way you want.  This patch is fine by me but
please don't imply that it fixes a run time error in the commit message,
which is what I first thought.

I see a discussion has sprung up on the best way to fix it so I guess
that has to be resolved first.
