Description:
------------
I thinks i have found a bug in the mysql_fetch_row, mysql_fetch_array and mysql_fetch_assoc functions.

When I select twice the same field with 2 different tags, mysql_fetch_* always return the same line.


Reproduce code:
---------------
<?php

include "conf.php";
$sql = "SELECT DISTINCT page as CHAMP, page as VALEUR FROM logs WHERE 1 ORDER BY CHAMP ASC";
$q = mysql_query($sql) or die (mysql_error());
while($foo = mysql_fetch_array($q))
{
	print_r($foo); echo '<br>';
}
?>


Expected result:
----------------
Array ( [0] => accueil.php [CHAMP] => accueil.php [1] => accueil.php [VALEUR] => accueil.php ) 
Array ( [0] => logs.php [CHAMP] => logs.php [1] => logs.php [VALEUR] => logs.php ) 


Actual result:
--------------
Array ( [0] => logs.php [CHAMP] => logs.php [1] => logs.php [VALEUR] => logs.php ) 
Array ( [0] => logs.php [CHAMP] => logs.php [1] => logs.php [VALEUR] => logs.php )
