er logs a message or unlinks the
	files, depending on a compile switch.  There are also some changes
	to anlwrk.c and uucp.h.  First, uuxqt.c


uuxqt.c log:
----------------------------
version 1.6        
date: 84/10/08 14:43:21;  author: joe;  state: Exp;  lines added/del: 2/1
Fix editing (really formatting) mistake which crept into v1.5
----------------------------
version 1.5        
date: 84/10/04 12:00:27;  author: joe;  state: Exp;  lines added/del: 3/2
Add log message for old X. files if UNLINK_OLDX is not defined.
This way, you can check the LOGFILE for old files and unlink them
by hand.
----------------------------
version 1.4        
date: 84/04/10 15:02:34;  author: joe;  state: Exp;  lines added/del: 2/0
Made unlinking of work files conditionally compiled on switch
UNLINK_OLDX.  Default is not to include the code.
----------------------------
version 1.3        
date: 84/02/29 14:04:53;  author: joe;  state: Exp;  lines added/del: 3/2
Fixed problem with previous fix whereby uuxqt would not process any
work files if the first one it encounters did not 'gotfiles()'.  I
moved the second iswrk call in gtxfile() to after the while loop which
looks for old X. files and conditionally return 0 if no work, otherwise
I go back and loop some more.

----------------------------
version 1.2        
date: 84/02/21 13:33:51;  author: joe;  state: Exp;  lines added/del: 23/0
Modified gtxfiles() so that if an X. file exists but does not have all
of its associated D. files and it is older than 1 day, we try to unlink
it to keep the X. queue from overflowing and messing up things.  Change
suggested by Tom Truscott via rlgvax.
----------------------------
version 1.1

anlwrk.c log:
----------------------------
version 1.2        
date: 84/02/21 13:32:26;  author: joe;  state: Exp;  lines added/del: 8/6
Moved LLEN and MAXRQST to uucp.h.  Made Nfiles global for use
by uuxqt.c/gtxfiles().

Obviously, you also have to #define LLEN and MAXRQST in uucp.h.  I leave
that as an exercise for the reader.
