I just *know* I've seen this before, but cannot remember the damned fix... 

This happens with both normal shell mode and cmushell mode, in epoch-4.2
on an axp running osf/1 rev 10. It does *not* happen  in the
distribution of GNU Emacs 18.58.13 that comes with osf/1. 

Whenever I start a {cmu}shell buffer, I see: 
	Warning: no access to tty; thus no job control in this shell... 
	~ 1 % 
Control-C, Control-Z, etc do not work (the shell appears to ignore all
interrupts). This does not happen in the Emacs distributed with osf/1,
so it would seem it's some build tweak for epoch on the axp, but I can't
figure which one. Does anyone know?
