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.
