Cs ability to run on "unconventional" (though there is little unconventional about the Lisp Machine, it is a just a stack based machine) long predates C89 (specifically). ZETA-C, a C compiler specific to the Lisp Machine, was already fully fledged by 1987 or there about. Don't have notes on when ZETA-C came to be, but it was much earlier than that, e.g., some of the headers are dated 1984. One cool thing about ZETA-C was you could embed Lisp code in between C code: extern FILE *stdin, *stdout, *stderr; #lisp ;; We don't want this file to "own" these (zeta-c:zclib>initialize-file-pointer |stdin| 0) (zeta-c:zclib>initialize-file-pointer |stdout| 1) (zeta-c:zclib>initialize-file-pointer |stderr| 2) #endlisp
