Hi magnum,

These look good to me, except that in cracker.c there's this redundant
piece left:

#if CRK_PREFETCH && defined(__SSE2__)
#include <emmintrin.h>
#endif

it becomes redundant with the addition of:

#if CRK_PREFETCH && defined(__SSE__)
#include <xmmintrin.h>
#endif

higher in the same file.  Please remove the __SSE2__ / emmintrin.h piece.

I think not.  Let's keep things as they are.

Thanks!
