From 3fc8df52e3856eeac730574d5ae122806dd1e1ef Mon Sep 17 00:00:00 2001
From: imp <imp@FreeBSD.org>
Date: Sat, 2 Feb 2002 06:36:49 +0000
Subject: o __P has been reoved o Old-style K&R declarations have been
 converted to new C89 style o register has been removed o prototype for main()
 has been removed (gcc3 makes it an error) o int main(int argc, char *argv[])
 is the preferred main definition. o Attempt to not break style(9) conformance
 for declarations more than   they already are. o gc some #ifdef sun ...
 #endif code

Approved by: arch@, new style(9)
