But I digress, I seem to recall reading in another thread here that AIX may have had a
fair deal of IBM stuff like perhaps some PL/I or PL/S down in the guts of significant

IBM what with their legacy in languages bristling at letting C be the star of the show.

For all our faults in the AIX team and IBM in general, there was no
desire to have legacy IBM languages as primary in AIX.

tries to explain why PL.8 code existed in early AIX and how PL.8 code
was eliminated in AIX 3 development.
AIX for the RT 1&2 bundled pcc (with the HCR optimization phase in AIX 2).
Since I left IBM in the midst of AIX 3 development, I'm not certain what
happened with compilers after I left. Part of the confusion was IBM
Toronto rewriting the Yorktown Research compiler to be a "product
worthy" C compiler. There may have been desire to gain revenue for the
Toronto compiler, but I assume that some some C compiler was bundled in
AIX 3.
