From 6329ef9e5d6f36ca3f7258279f6640037b71926a Mon Sep 17 00:00:00 2001
From: Chih-Wei Huang <cwhuang@linux.org.tw>
Date: Tue, 10 Feb 2015 14:55:20 +0000
Subject: Add missing guards around config.h inclusion

In some cases the header may not exist, leading to compilation issues.
Add the ifdef HAVE_CONFIG_H, as it is those in other parts of the
project.
