I don't know what this "pcc2" you're referring to is. 4.3 shipped with
the VAX version of the plain old "pcc" compiler from Bell Labs, and it
just plain sucked. I have great difficulty believing you when you claim
that it produced better code than gcc; if that is true, GCC has gotten
far worse on the VAX than it once was, and I don't really see any reason
why that would be the case.

That is just plain false.
