From aa9caaf65748ace0f3cd08c2deaf3ef3048d6e4d Mon Sep 17 00:00:00 2001

Subject: Merge of 4.4-Lite2 sh source, plus some gcc -Wall cleaning.  This is
 a merge of parallel duplicate work by Steve Price and myself. :-]

There are some changes to the build that are my fault...  mkinit.c was
trying (poorly) to duplicate some of the work that make(1) is designed to
do.  The Makefile hackery is my fault too, the depend list was incomplete
because of some explicit OBJS+= entries, so mkdep wasn't picking up their
source file #includes.

This closes a pile of /bin/sh PR's, but not all of them..
