I don't use a Mac but my understanding is that MacOS
X is basically just Mach with a BSD-style personality
called Darwin.  As apparent confirmation of that,
the guy at the desk next to me (who's running MacOS X)
just now cat'd out the /etc/passwd file on his machine
at my request.  Note that he'd never had occasion to
care about it before this and wasn't even sure it
would be there, though he's built code with gcc on
that machine and even installed Debian packages on it.
