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.
