Remember my inquiry as to what effect cc -O has under
Edition VII, since the manual says it's not implemented
but /lib/c2 exists? Well, I noticed that /lib/c2 has two links,
and ncheck reveals it's a link to /bin/cp. Cute.
So, using the -O option to cc does nothing except slow the
compile down by the time it takes to copy the object module
over once with cp.

I think the reason that the -O option exists at all is because it was a simple
matter to replace the optimizer program (c2) with a link to copy rather than
hack up the source code. Another thing you might want to watch out for is
the multiple defines caused by the SCCS headers in the /usr/include/* files.
I always do "cc -DNO_SCCS_ID -m" just to get around most of the errors. It
seems to help a lot.
