Well, I don't know if there is such a reason. Probably Thomas spent too
much time in the BSD sources :)

But let me point out that bcopy is equivalent to memmove, not memcpy
(which doesn't handle overlapping regions).

I can't answer that for the core developers, however, is there a particular
reason beside cosmetic? Of course, if you bother to find out where memcpy
is sufficient instead memmove/bcopy, it might be a small performance
advantage.

Thanks,

development of the Hurd is discussed rather than the binary distribution.
