I recall the Portable C compiler was not the original, There was
an earlier C native to PDP11, not portable; pcc was the rewrite to
make it portable at the expense of inefficiency.
Before C there was B
( which had some relation to BCPL http://en.wikipedia.org/wiki/BCPL
told me by Bob Eager, in Canterbury, Kent, England, decades back)
Yet another C compiler (or 2 ?):
Munich, Germany, 1985:
Siemens was already licensing a C compiler from an American chap,
(I can't remember his name). Siemens shipped it with their Sinix,
a Unix that ran on i386 & ns32000 series. Their Sinix had
translations integrated in seven human languages (my job).
A few years on, Terry Carroll in Munich was trying to sell his own
C compiler [bits (not sure if he got to a whole compiler)].
