I just got GNUmacs version 64 running on an elxsi, under 'enix'
which is a System V.2 clone.  Hooray.

But...  When I use shell-interaction mode, I can't send EOF to
a subprocess of the shell.  Since the shell is getting its input
from a pipe, it doesn't do all the fancy line-discipline processing
that it would with a terminal.  In particular, sending it ^D disturbs
it not in the least.  I tried to go into process.c and just close the
file descriptor, but that loses because the pipe is closed to the
shell, not the sub-process you are interested in.  Is there any solution?
Does System V have something resembling pseudo-terminals that I don't know
about?

A different problem:  When I try to use rmail, count-messages (or one
of its friends) assures me that there are no new messages.  This is a lie.
I'm pretty sure I've told it the correct mail file to look in.  I think
it is unable to find message delimiters in the system mailbox.
Is this a common problem with rmail on SysV?  Am I missing something obvious?
Thanks.
