;;; BUG REPORT NUMBER:  10423
;;;
;;; PROBLEM:  
;;;	The package "GLOBAL" does not include the symbol NIL.  This will cause
;;;	serious problems for Zetalisp programs that use the GLOBAL package.
;;;
;;; SOLUTION:  The following fixup code removes the bogus internal symbol 
;;;	GLOBAL::NIL and exports LISP:NIL from the GLOBAL package.  A source fix is 
;;;	not required because the problem was caused by a previous patch [6.13].
;;;
;;; DEPENDENCIES:  Must be loaded after patch System 6.13.
