title: identifier "__builtin_expect" is undefined (during ROS on win tutorial-talker example)
body: <p>I'm trying to do the <a href="http://wiki.ros.org/win_ros/hydro/Msvc%20SDK%20Projects" rel="nofollow noreferrer">first tutorial of ROS</a> on Windows in Visual Studio 2015.</p>
  
  <p>First I created a new WIN 32 Console application and copied the code from <a href="http://wiki.ros.org/ROS/Tutorials/WritingPublisherSubscriber%28c%2B%2B%29#roscpp_tutorials.2BAC8-Tutorials.2BAC8-WritingPublisherSubscriber" rel="nofollow noreferrer">here</a>.
  Then I configured the project as it is described in the guide. While Debugging there came up several errors:</p>
  
  <ul>
  <li>The identifier "<code>__builtin_expect</code>" is undefined in the files <code>service_client.h</code> and <code>TestTalker.cpp</code> (which is the name of my program).</li>
  <li>Cannot open source file "sys/time.h"</li>
  </ul>
  
  <p>The SDK from <a href="http://wiki.ros.org/win_ros/hydro/Msvc%20SDK" rel="nofollow noreferrer">wiki.ros.org</a> runs, I tested it.
  I have no idea what's wrong.
  I hope someone can help me.</p>
  
  <p>Thank you in advance!!</p>
