From f418b6577e744bfa0c97476aa5d3d3fe8a5bcf8e Mon Sep 17 00:00:00 2001
From: csgr <csgr@FreeBSD.org>
Date: Tue, 11 Oct 1994 11:29:17 +0000
Subject: - remove unnecessary #includes (I think a couple of redundant ones
 remain) - excise some unused code (#if 0'd out - don't want to nuke it yet) -
 fix problems with "make depend" - some macros were screwing it up - get rid
 of some static local variables

There still seems to be a small reentrancy problem somewhere.
