From 696fbe6b0565b95bee329a2697d40b58b3459052 Mon Sep 17 00:00:00 2001
From: Mike Barcroft <mike@FreeBSD.org>
Date: Fri, 4 Oct 2002 21:31:33 +0000
Subject: [PATCH] o Adjust the SEM_VALUE_MAX macro so that <machine/limits.h>
 isn't   needed. o Remove unneeded includes which only add namespace
 pollution. o Sort function prototypes. o Add restrict type-qualifier to
 sem_getvalue().
