From f9fc827448679cf1d41e56512c34521bf06ce37a Mon Sep 17 00:00:00 2001
From: wollman <wollman@FreeBSD.org>
Date: Thu, 18 Aug 1994 22:36:09 +0000
Subject: Fix up some sloppy coding practices:

- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
  header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.
