When I compile the below code with VC++ and -Ox-optimizatzions the
comparison is inlined and the memcpy won't be called, but instead
a single 4-byte-copy is done. So the performance is only slightly
worse than the int-specialized version.
But if I compile the code without global optimizations the whole
algorithm is 2,5 times slower than the int-optimized version.
