Just recompiled. I don't think this was one he had to make any changes
too. As Mary Ann and I said, Kurt wrote as part of the UCB Mail
package [which includes delivermail(8) - which was the moral parent to
sendmail(8)].
fmt was literally part of Mail - it compiled in the same source
directory, and was considered user agent (UA) code. delivermail/sendmail
was separate, also from Berkeley, but written primarily by Eric Allman,
and was the mail transport agent (MTA). It's in 2.8BSD as well.
The whole key is that Keith did not have a Vax at the
Math department
(they had an 11/70 with max memory) and wanted all of the cool
programs that were being created on the Vax. Remember, VM is
automatic overlays. So first with the kernel, and then later with
user code, larger and larger programs were enabled and many of the
programs for the Vax migrated to the PDP-11, as people ran out of
address space (IIRC: one the first user programs that needed to use
overlays was ex/vi. Again, as I recall the original wnj version by
then was such a mess, getting a new/cleaner code base was a large
impetus for Keith to start writing nvi).
ex/vi didn't use overlays (unless you count split I/D). It fit in 64
bits by using ifdefs. Less useful code, like supporting upper-case-only
terminals, would be ifdeffed out on the pdp11.
