Another DEC compiler that I forgot was the original C compiler for
Tru64 Unix on the Alpha. This was done at the DECwest facility in
Seattle (which originally had been set up by Dave Cutler). It was a
very strict implementation of the ANSI C89 standard--it had no
extensions such as K&R support. One customer called it the "Rush
Limbaugh of C compilers" because it was extremely conservative and you
couldn't argue with it.
