I'm glad that you qualified it with "for the time"; I've used it, and
calling it a "C compiler" was a bit of a stretch[*]. Later on I bought
the Hi-Tech C compiler, and it was full ANSI, with function prototypes
etc.

Hmm. K&R publication date was February 1978. BDS C was released in August 1979. So it was certainly C as known at that time. X3J11 was convened in 1983 and published in 1985. Doesn't seem like a good comparison.
