Subject: Bug in initstate in random.c
Index:	libc/random.c 4.3BSD-tahoe from UUNET a while back

Description:
	There is a bug pointed out by Scott Garfinkle in the random.c file.
	This was gotten from UUNET some months back, perhaps it has been fixed
	since then.

	In initstate, if there isn't enough room, it just returns, instead of
	explicitly returning a null pointer.
Repeat-By:
	Call initstate with not enough room.
Fix:
	Apply the following patch.
