From 246190a1806a7d045f8038742b61cdc2b517db8e Mon Sep 17 00:00:00 2001
From: Kenneth G Raeburn <raeburn@mit.edu>
Date: Thu, 21 Mar 1991 07:19:18 +0000
Subject: Include varargs.h or stdarg.h as appropriate.  Test new
 Z_HaveKerberos macro instead of KERBEROS.  Defined Zconst to `const' or
 empty. Declare new ZNoticeKinds array, addressable versions of macros, debug
 routines/macros/vars.  Conditionalize Kerberos-related stuff better.
