Porting sccs.c to AT&T UNIX V.2.

[Mark D. McKamey IM SA]

Hello,
 
    I am in the process of porting Eric Allman's "sccs.c" - human-oriented
front end to the SCCS system program, to a UNISYS 5000/80 mini, running
AT&T UNIX V.2 Operating System.  I have changed <sys/dir.h> to <sys/ndir.h>,
and also changed "index" to strchr, and "rindex" to strrchr.  Upon compilation
I get the following error message:

	undefined symbol - sys_siglist

    Does anyone have this library routine for AT&T UNIX V.2 ?  If so,
please e-mail me a copy.  Thank You,
