CSS/Harvard 2.9BSD bug report #4

[Keith Bostic]

Subject: SSUBM isn't defined
Index:	sys/acct.c sys/slp.c 2.9BSD

Description:
	If you define UCB_SUBM in localopts.h, routines like acct.c and
	slp.c don't have the flag SSUBM defined anywhere.
Repeat-By:
	Define UCB_SUBM in localopts.h and attempt to recompile the kernel.
Fix:
	None.  As far as I can tell, SSUBM was never defined, so your guess
	as to what it should be is as good as anyone elses.  UCB_SUBM is a
	2.9 specific define that has to do with the submit(2) and killbkg(2)
	calls in the C library.  Since the calls are not implemented in 4.[23],
	I suspect that it will go away in my version of 2.9 and any future
	releases Harvard and/or I make in the future.  Job control and "stty
	nohang" pretty much cover the ground.
