Well, it was yoshfuji's patch that suggested the change explaining
that memcmp() is slow.

If joshfuji suggests a change like that, I think he is
pretty sure that for all archs' memcmp() of 4 integers is slower
than simply comparing them.

Anyway I was not aware of such a multiplicity of memcmp() and friends
implementations for different archs. Good to know :-)

Maciej
