But the earliest C compilers didn't. I know, because I used one around
1979. My college was running a verly early version of UNIX on a PDP-11/45.
We had terminals that printed out on rolls of paper, upper-case only. In
addition to not having unsigned arithmetic, the compiler was primitive in
many other ways. For instance, no two structures (records, for you Ada
folks) could have a field with the same name if they were at different
offsets from the beginning. It didn't have unions either. It was quite
the occasion a couple of years later when we got a full K&R compiler
(and video display terminals, which even supported both cases!)
