I'd agree to both. Mind you, once you start patching, where do you stop?
We could bring V6 up to being POSIX compatible with an ANSI C compiler :-)

Seriously, at one stage I did think of trying to check-in every version of
UNIX we have into a single CVS repository. Problem is, files have moved
around, and I want to leave gaps just in case we ever get the missing versions.

I might ask Dennis for the details. From memory, the binaries never got out
of the Labs, and it would have been around the time of V6. Also from memory,
this was the topic of Ken's speech when he won the Turing award. I wonder if
the article is lying around somewhere.
