I can't remember who sent in that configuration - it was some time ago -
and I do not myself have access to any DG systems.

The first of those is very easy to fix, but you can in the meantime
override it by setting OSTYPE=DGUX. The lack of sysexits can be coped
with as for some other systems.

Aarrgghh!! No! You shouldn't set LINUX_IP_OPTIONS unless you are running
on Linux.

Indeed.

I'm afraid I can't. I suppose you could just try not including
netinet/ip_var.h and see if you get what you need from other headers.
A less safe alternative is to cut out all the ip_options testing in
smtp_in.c, as is done when HAVE_IPV6 is set (but don't whatever you do,
set that!). However, that does open you up to some forms of abuse of
TCP/IP.
Any DG-UX experts on this list?
