I'm not sure.
Allen mentioned /var/mail/root, which implies he's having trouble concerning
email delivery to the root _mailbox_ . AFAICT (at least on Debian) mailboxes
are owned by <user>:mail (root:mail for the root mailbox), with permissions
rw-rw---- meaning that the mailboxes are all writable by the 'mail' group;
however on Debian Exim runs under the "Debian-exim" user, and by default is
not part of the 'mail' group.
I think the combination means that Exim has to gain permission as each user in
order to deliver mail to their respective accounts, and can't do this for the
root mailbox because Exim is banned from becoming the root user.
However it's customary to redirect root mail via /etc/alases to a normal user
account, which will get around this issue without any other reconfiguration or
recompiling necessary. So Allen -- this is what I'd recommend.

Looking at the Git repo, still seems to be available:
cknadle@Trelane:~/src/Exim_upstream_git/exim$ fgrep -r FIXED_NEVER_USERS *
...
src/src/EDITME:# FIXED_NEVER_USERS=root:bin:daemon
src/src/EDITME:FIXED_NEVER_USERS=root
src/src/config.h.defaults:#define FIXED_NEVER_USERS "root"
src/src/globals.c:uid_t fixed_never_users[] = { FIXED_NEVER_USERS };
