There was also a "Small C", see DDJ #45 (May 1980), "A Small C Compiler for the 8080s" by Ron Cain[4]. Cain references buying a copy of "the Tiny-C interpreter from Tiny-C Associates" and finding it too slow, so he bootstraps his own C compiler, writing it in C, compiles it on a UNIX system, then using it to compile itself to get the 8080 machine code.
See also DDJ #69 (July 1982) p. 66, "Small C for the 9900" by Matthew Halfant[5], porting Cain's compiler to another platform.
To be clear, I'm not claiming to be the first to have used the name Tiny-C, just that the confusion with TCC is not intentional. Your links to DDJ are great an bring back memories of the good old days when there was much to learn from reading DDJ and Byte magazine!
