if cfront is of interest v3.0 and i think v3.1 are available here:
http://www.softwarepreservation.org/projects/c_plus_plus

i did manage to get the final version to run on plan9 but it supports no modern constructs and so was little real use.

Thank you.  Very interesting.

Now if only I could find the unix source for Tom Duff's rc shell in there.
Or maybe I'm overlooking it?

I didn't find it so far, the manpage is there though.

Other fun things I saw on a quick tour are in v10blit:
src/jim

in v10src:
cmd/movie
cmd/cyntax
cmd/monk
cmd/dag (precedessor of dot?)
cmd/cfront/cfront2.00
