title: Static variables end up in Doxygen docs when they shouldn't
body: <p>I've started using Doxygen for a C project.  I have set both EXTRACT_ALL and EXTRACT_STATIC to NO. Still, some of my file-level static variables show up in the documentation that Doxygen generates.</p>
  
  <p>Of this block of definitions, <code>fps_ypos</code> and <code>fps_height</code> are included in the docs:</p>
  
  <pre><code>/* properties of the frames per second text */
  static int fps_xpos, fps_ypos;
  static int fps_length, fps_height;
  static bool show_fps = FALSE;
  </code></pre>
  
  <p><code>bool</code> is a typedef for <code>unsigned char</code>, if that matters.  This is MSVC C, not C99.</p>
  
  <p>Anyone know what can cause this or what I can do to fix it?</p>
  
  <p>By the way, I'm using Doxygen 1.7.5.1 on Windows.</p>
