Subject: [PATCH] Bug#53445: Build with -Wall and fix warnings that it

If bzero is not available, resort to memset. Also, remove dead

-/*  File   : bzero.c
-    Author : Richard A. O'Keefe.
-	     Michael Widenius;	ifdef MC68000
-    Updated: 23 April 1984
-    Defines: bzero()
-
-    bzero(dst, len) moves "len" 0 bytes to "dst".
-    Thus to clear a disc buffer to 0s do bzero(buffer, BUFSIZ).
-
-    Note: the "b" routines are there to exploit certain VAX order codes,
-    The asm code is presented for your interest and amusement.
