other things):

This passage tickled something in my memory and I wanted to  hear from
those who really know.  I don't believe that "rcc" is actually a
Microsoft invention but rather is the name of the 3rd generation
compiler based on the original portable C compiler, pcc.  I even seem
to recall that there was some discussion of an "scc", which I assume
would be the 4th generation of the same compiler family.

Is "rcc" an AT&T derivative of "pcc"?
