FWIW;
I think the posix manpage is in the right direction.
For a more detailed discussion about replacing bcopys you may read Ted
Unangst's
blog post[1], but of course OpenBSD is not FreeBSD.
I honesly would sepnd much time in bcopy, it is one of those things that
will stay
in FreeBSD for a long while. I would focus on strtoq() and strtouq()
which carry
this *comical* notice in stdlib.h :
/* Deprecated interfaces, to be removed in FreeBSD 6.0. */
Cheers,
Pedro.

Hi David,
So it means, this commit here was right already:

Although I made a mistake with the date.
All the best.

Its use should be strongly discouraged in FreeBSD (or, ideally,
replaced with the macro from the POSIX man page). LLVM does a
load of optimisations for memmove and memcpy - using bcopy is a
really good way of bypassing all of these.
