I thought SVR3's was PCC (maybe PCC2).  But I thought I remember that is
had a i386 code.  Certainly by SVR4 time.
IIRC, the time frame of SVR3's front end would have been original ANSI
(i.e. White Book V2).

In the time frame of the SVR3 (mid/late 80s), the Intel processors was
faster than the 1MIP (780 circa 1977) in raw computes.  The issue was
always I/O.  Most PC did not have the same amount of I/O HW that much
earlier Vaxen.

And my point is that by the time of C99, it was a different language than
the early 1970s when Dennis created fit or the original PDP-11/20  he and
Ken used for the first UNIX kernel and tools implementations.

"When I read commentary about suggestions for where C should go, I often
think back and give thanks that it wasn't developed under the advice of a
worldwide crowd." dmr
