From 044228d5ecb9b79397f9fc915d046cf4538281e2 Mon Sep 17 00:00:00 2001
From: Eric Andersen <andersen@codepoet.org>
Date: Tue, 17 Jul 2001 01:12:36 +0000
Subject: [PATCH] This is vodz' latest patch.  Sorry it took so long...     1)
 ping cleanup (compile fix from this patch already applied).     2) traceroute
 call not spare ntohl() now (and reduce size);     3) Fix for functions not
 declared static in insmod, ash, vi and mount.     4) a more simple API
 cmdedit :))     5) adds "stopped jobs" warning to ash on Ctrl-D and fixes
 "ignoreeof" option     6) reduce exporting library function index->strchr
 (traceroute), bzero->memset (syslogd)
