No, it does not. It is just an optimization because I happen to have 603e
and the default scheduling is bad on it (it tends to expand multiplies to
series of shift and add since it believes that multiplication is much more
expensive than it actually is on most PPC processors). Scheduling on 750
is probably different but this should not have any major adverse
effects.  

However this problem is obviously my fault, I did not track some changes
:-( You should include linux/string.h instead of string.h.
