From 9a75c748367c2ff84de355b136c33760a6b6928a Mon Sep 17 00:00:00 2001
From: Russ Cox <rsc@golang.org>
Date: Fri, 29 Aug 2014 16:00:31 -0400
Subject: runtime: include constants and defs_*_*.h types in generated Go defs

I had to rename Kevent and Sigaction to avoid the functions of the
same (lowercase) name.
