Description:
------------
A bug that has been reported and fixed in the past regarding getopt not 
resetting after being called once has resurfaced.

Here's the original bug: http://bonsai.php.net/bug.php?id=29714

The same behaviour is happening in 5.3.1 - once getopt has been called, 
subsequent calls ignore options not included in the original call.



Reproduce code:
---------------
> php test.php -d hello -b world

<?php
$options = getopt("d:");
print_r($options);

$options = getopt("b:");
print_r($options);

Expected result:
----------------
Array 
(
    [d] => hello
)

Array 
(
    [b] => world
)

Actual result:
--------------
Array 
(
    [d] => hello
)

Array 
(
)
