 * HISTORY

 * Revision 1.7  89/04/03  11:10:45  vanryzin
 * 	Changed definition of qsort for c++ to indicate the procedure
 * 	passed to qsort has parameters.  Since we were unsure if ANSI C
 * 	could handle the syntax I placed the new definition within #if
 * 	defined(c_plusplus) conditionals.  This may not be necessary
 * 	and perhaps should be fixed at a later time.
 * 	[89/04/03            vanryzin]
 * 
 * Revision 1.6  89/02/05  15:55:57  gm0w
 * 	Added extern char *errmsg().
 * 	[89/02/04            gm0w]
 * 
 * Revision 1.5  89/01/20  15:34:40  gm0w
 * 	Moved all of the STDC changes to other existing include files
 * 	back into this one.  Added non-STDC extern declarations for
 * 	all functions without int return values to match those defined
 * 	by STDC.  Added include of sysent.h.  Removed obsolete cdate
 * 	extern declaration.
 * 	[88/12/17            gm0w]
 * 
 * Revision 1.4  88/12/22  16:58:56  mja
 * 	Correct __STDC__ parameter type for getenv().
 * 	[88/12/20            dld]
 * 
 * Revision 1.3  88/12/14  23:31:42  mja
 * 	Made file reentrant.  Added declarations for __STDC__.
 * 	[88/01/06            jjk]
 * 
 * 30-Apr-88  Glenn Marcy (gm0w) at Carnegie-Mellon University
 *	Added pathof() extern.
 *
 * 01-Dec-85  Glenn Marcy (gm0w) at Carnegie-Mellon University
 *	Added getname() extern.
 *
 * 29-Nov-85  Glenn Marcy (gm0w) at Carnegie-Mellon University
 *	Added lseek() extern.
 *
 * 02-Nov-85  Glenn Marcy (gm0w) at Carnegie-Mellon University
 *	Added estrdup() extern.
 *
 * 14-Aug-81  Mike Accetta (mja) at Carnegie-Mellon University
 *	Created.
