You are right about gcc; version 1.37 (and I think a later version too)
was ported to MPW, where it performed better than, and was more or less
a drop in replacement for, Apple's compiler. In fact, when I was porting
TeX -- at the time, considered a large program -- only gcc would compile
it successfully.
Long before that, I used Whitesmiths C, Aztec C, and of course
Lightspeed/THINK C on Mac for 68K.
