For no good reason, I've been wondering about the early history of C compilers that were not derived from Ritchie, Johnson, and Snyder at Bell. Especially for x86. Anyone have tales?
Were any of those compilers ever used to port UNIX?
MIT had several that were used for ka9q and at least the Venix x86 port. They supported the popular micros of the time. Various versions of them survive to the present day.
