$NetBSD: patch-ba,v 1.8 2011/05/21 15:33:00 wiz Exp $

1. chunk:
Check NetBSD's native atomic_ops in configure even in arm case.
configure checks $host_cpu first, not $host_os on checks for
native atomic operations.
(In upstream it seems fixed to see $host_os first but
 it might still have problem around NetBSD version checks)

2. chunk:
Fix for security vulnerability reported in CVE-2009-1299, taken from here:
