From c8a08e056ff2a0f7268ba7df647b69afcc26d11e Mon Sep 17 00:00:00 2001
From: jwise <jwise@NetBSD.org>
Date: Thu, 4 Jan 2001 03:51:23 +0000
Subject: [PATCH] More rationalization of include files:

a.) Don't include a zillion system headers from "extern.h" (actually, don't
    include any).
b.) Break a global jmp_buf variable into a new file, so <setjmp.h> doesn't
    have to be pulled in everywhere (it's only used in two places).

The (one line) new file is (c) TNF with a three-clause license, FW(L)IW.
