From c9e7ce2fe1e739a349fd78a136e6da0b1fecf65f Mon Sep 17 00:00:00 2001
From: David Chisnall <theraven@FreeBSD.org>
Date: Sun, 13 Nov 2011 16:18:48 +0000
Subject: [PATCH] The spec says that FILE must be defined in wchar.h, but it
 wasn't.  It is now.  Also hide some macros in C++ mode that will break C++
 namespaced calls.
