title: Drupal 7 and Classified Ads module error
body: <p>i'm testing drupal 7 with the Classified Ads module but after module installation, i got a boring error : </p>
  
  <ul>
  <li>Notice: Constant REQUEST_TIME already defined in include_once() (line 34 of /var/www/chri/sites/all/modules/ed_classified/ed_classified.module). </li>
  </ul>
  
  <p>When i took a look at the php code i wasn't able to find the problem cause the following function is not supposed to define REQUEST_TIME if already defined...</p>
  
  <pre><code>/*
   * Drupal 7 provides REQUEST_TIME as time of start of request. This
   * is more efficient than using time() every time. Adopted here.
   */
  if (!defined(REQUEST_TIME)) {
    define('REQUEST_TIME', time()); //LINE 34
  }
  </code></pre>
  
  <p>Any suggestion ?</p>
