Description:
------------
When using a prepared statement, the num_results will return 0  even if a result is returned.  I am using PHP 5.1 with MySQL 5.

Reproduce code:
---------------
				$stmt = $mysql->prepare('
									SELECT
										cur_start
									FROM
										track
									WHERE
										id = ?
										;');
				$stmt->bind_param('i',$_GET['id']);
				$stmt->execute();
				$stmt->bind_result($m_id,$m_cur_start);
				$stmt->fetch();
				// a value is printed out here clearly indicating that a row is returned
				print $m_cur_start;

				if ($stmt->num_rows != 1) // this is always 0!
				{

Expected result:
----------------
$stmt->num_rows should be 1, in this case.

Actual result:
--------------
$stmt->num_rows is always 0.

Sorry, my reproduction code contains a bug (left over when I was taking out unnecessary code).  Bind result should only have $m_cur_start in it.  But you get the idea.
