title: Only show errors from compilation in Eclipse CDT
body: <p>In <em>Problems</em> I see errors from compilation (with gcc) and from Eclipse internal parsing. There are actually some errors from this parsing that do not show up in compilation.
  I do not care about fixing this parsing, but I would like these errors not to show up.</p>
  
  <p><strong>How can this be done?</strong></p>
