if ( $chfile !== False )
{
    print "| <a href=\"" .
        htmlentities($base_url) .
        htmlentities(preg_replace("!.*" .
            preg_replace("!.*(/[^/]+/?)$!",
            "$1",
            $base_url) .
            "(.*)!", "$1",
            $changesdir) .
            "/" . $chfile) .
        "\">Changes</a>" . "\n";
    break;
}

The preg_replace calls might be the problem.
