Fine. So what? I didn't make that claim. The 4.3BSD team implicitly
did, though. (See the kernel's program logic manual, _The_Design_and
_Implementation_of_the_4.3BSD_UNIX_Operating_System_.)

That may be true. I don't really know because I haven't looked at
Darwin source. However, essentially everything in NextStep above the
kernel that was not part of the OOPS was taken directly from 4.3BSD.
Perhaps Apple has since replaced all that software with the FreeBSD version.
But even so, much of FreeBSD came directly from 4.[34]BSD anyway. I've
glanced at a few of the header files in Mac OSX libraries, and they are
still chock full of labels beginning with "NS" or "NX". :-)

Keep in mind that Mach 2.x *was* a heavily modified 4.3BSD kernel.
Mach 3.x and later is not.

I see. So is it just the GUI that's missing in Darwin? Or is the
entire OOPS missing? I guess it's nice to know that the underlying system
is available for the pee cee architecture, but it couldn't be nearly as fun
without the OOPS. :-)
