Pcc, pcc2, stincc, qcc and rcc are, in historical order, versions of
the same compiler. (Although pcc and pcc2 coexisted for a while.) The
major differences between them were in their code generators.  The
biggest break was between pcc and pcc2, since the latter introduced a
"stin file" containing code generation templates.

These names were used internally to mark significant changes.
No distinction was ever made externally, and there were many changes
that were not marked by a name. In general, the more recent the
compiler the "better".

All of these are AT&T code. NONE of these is in the public domain.
Mostly, source licences are only available as part of a UNIX source
licence.
