Disable RSS Feed Icon

Drupal's 5.7 default has the orange rss feed icon. For websites that are more 'brochure like' and do not want this feature, we have to manually 'remove' this by editing 2 files:-
(1) public_html > includes > theme.inc and
(2) public_html > includes > common.inc

Comment Out (Remove) Codes Like Below

Edit theme.inc to disable feed icons

function theme_feed_icon($url) {
//  if ($image = theme('image', 'misc/feed.png', t('Syndicate content'), t('Syndicate content'))) {
//    return '<a href="'. check_url($url) .'" class="feed-icon">'. $image. '</a>';
//  }
}

AND also edit common.inc

function drupal_add_feed($url = NULL, $title = '') {
  static $stored_feed_links = array();

/*  if (!is_null($url)) {
    $stored_feed_links[$url] = theme('feed_icon', $url);

    drupal_add_link(array('rel' => 'alternate',
                          'type' => 'application/rss+xml',
                          'title' => $title,
                          'href' => $url));
  }*/
  return $stored_feed_links;
}
