Franz, I still don't see why the divide routines can't
stay in the GLIBC_2.0 version.  You say you saw "this"
in "the wild", but don't actually describe the failure
mode.

I don't like the patch much either.  I'm sure it would be
better to do it from the source level inside libgcc2.c.
Though it would still be a hack.

Jakub, this patch looks right.

Yes.

Hum.  The patch I remember doesn't seem to have been written. :-(
As discussed on the thread, __m64 needs to be a vector type so 
that the x86-64 calling conventions put it in the right set of
registers.  Which means a large repetitious patch to mmintrin.h.
