A few of the folks at work have 10.1 still installed (Darwin 5.0), and
it
has the netinet/ip_var.h header file. So this would have to be
different.

True, I was just trying to be consistent with what I saw in the
codebase.
I mean, it may not be necessary to change as that it was pointed out
earlier that cc is simply linked to gcc for backwards compatibility
reasons.

I still don't know the answer to this yet, but as that I am not running
a full
blown mail relay and using Exim solely for outbound mail on my laptop,
I am not too worried about this. By defining both the

#define NO_IP_VAR_H
#define NO_IP_OPTIONS

in the header file, the software built fine and is working great.

Once I have the answer to your IP options question above, I will
post my findings to the list and you can let me know what you'd like
to do and I'll post whatever is appropriate.

Thanks again for your help Philip!
