That's an obsolete notion of what BSD is ... memory.h appeared in BSD
in 4.3 (years ago).

There's not supposed to be any noticeable difference between the BSD
mem*() functions (which is what memory.h is all about) so you should be
able to simply copy (or link) the ATT universe memory.h into the UCB
universe on a pyramid.  Unfortunately, I suspect that this may be just
pushing the problem back one layer, as if memory.h isn't in pyramid's UCB
universe, then its almost certain that the mem*() functions aren't in the
libc in its UCB universe either.

You may be able to get around that by linking with the ATT universe libc
*after* the UCB universe libc - which means that you'll need to explicitly
name that on the cc (or ld) command line, not just default to it.

The BSD mem*() functions are supposed to be exact functional duplicates
of the Sys V versions - though the true BSD versions don't make any pretence
to be effecient - they were just added to make it easier to move Sys V
progs to BSD, and in general improve compatability between the two).

ps: I'm pretty sure of all of this, except what might work on the
Pyramid, as I put all this stuff in BSD just before 4.3 was released.
