I agree that V6 had this misfeature (and AT&T corrected it in V7, which
is the basis for all modern UNIX systems).  However, if you did find
a V6 PDP-11 to port to, I would wager that this might be the least of
your troubles.  Both C and UNIX have changed a lot from those days.  I
wonder if there is any V6 systems still used for development these
days (I can believe that some are still chugging away on applications
written back then....).
