Bug#757268: ddccontrol: FTBFS with clang instead of gcc

[Arthur Marble <arthur@info9.net>]

Package: ddccontrol
Severity: minor
Tags: patch
User: pkg-llvm-team@lists.alioth.debian.org
Usertags: clang-ftbfs

Hello,

Using the rebuild infrastructure, your package fails to build with clang
(instead of gcc).

Detected this kind of error:
http://clang.debian.net/status.php?version=3.4.2&key=UNDEF_REF

Full build log is available here:
http://clang.debian.net/logs/2014-06-16/ddccontrol_0.4.2-11_unstable_clang.log

Thanks,
Arthur
