Well, I dunno, since the actual needed position in the key may not be
necessary a multiple of system-word size. Does that sounds correct ?

I now found a way to not use BE_32 on the keys, so that is actually
obsolete. That question would be just for my personal interest to know
that it is correct C coding.

Im just waiting for a tiny go from Mans, Michael or someone else to
commit and then start to mod.

Thanks Rich.
