The "You have mail" message is printed by /bin/login, not the cshell.  Thus,
you'll see the message if you rlogin to an apollo.  It might also print
the message in the DM output window if UNIXLOGIN is set at boot time
and /etc/motd is empty (I haven't tried it).

I re-installed the C compiler on top of an existing Domain/IX (both SR9
release) with no ill effects - The scripts appeared smart enough to
do the "right thing", and the documentation probably just assumes both
were shipped at once.

[Actually, there was one "ill effect" - the new C compiler's
/usr/include/math.h is missing a definition for "frexp", which somebody
here had added by hand to the Domain/IX version.]

    Now, we just received all new versions of optional software (PAS,FTN,C,D3M...)
    and the C install guide says that for both DOMAIN/IX and C to be running,
    you must install C first, then DOMAIN/IX.

    Does this leave me with no alternative but to reinstall domain/ix after I
    install C, or even worse, do I have to delete domain/ix, install c, then
    install domain/ix?

In spite of my return address, this is personal opinion, not any kind
of official reply.

My guess is that the point of contention here is the include files in
/usr/include.  You don't get as many of them with the C product as you
do with domain/ix.  If you were to install domain/ix first, then the C
installation would wipe out the domain/ix include files.
