note 51547 added to function.setcookie

I want to share a problem that took me one entire day to solve. This isn't about PHP specifically I guess, but the world *need* to know. If you try to put a cookie (this also apply for a session through cookie) from a subdomain with and /underscore/, like http://my_subdomain.domain.com/ this *won't work* under IE 6 for some reasons.
