title: silence -Wparentheses-equality error
body: <p>Im building som software using boost 1.48 on osx 10.8 with gcc version 4.2.1 and i have started getting <code>-Wparentheses-equality</code> warnings for some of the boost source.</p>
  
  <pre><code>  equality comparison with extraneous parentheses
    [-Werror,-Wparentheses-equality]
          else if((state-&gt;type == syntax_element_long_set_rep)) 
  </code></pre>
  
  <p>I would change the code but i dont want to tinker with the library, how would i silence the warning and make the compiler continue?</p>
