- Well, I don't think C was five years old until 1977-78. The B compiler
- was written by Ken Thompson in 1970 (1). Unix was re-written in C in 1973.
- (2).
-
- However, in 1978, apart from the PDP-11, "C compilers run on a wide
- variety of machines, including the Honeywell 6000, the IBM System/360,
- and the Interdata 8/32."(3)
-
- Sounds like about where Ada was ten years later, no? In terms of
- compiler availability, that is.
-
- I surmise that the original poster meant that during the first five
- of Ada compiler availability, C was a better supported language in
- terms of compiler availability and tool support. Hardly a revelation,
- since it's a smaller language and roughly a decade older.
