Bug description:  Bit operators not responding equally

Description:
------------
** Sorry if I havfe put this in hte wrong category.

I have encountered a difference in the output of a bit operator
combination between windows and FC3.  

The example below is part of the code that produces the Google Checksum
when submitting to get a page rank. 

 In Mozilla Javascript and windows Javascript and well as PHP 5.1.4 on
whindows XP the bit operation returns correclty but under linux there is a
difference

I don't no why.

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

$a = -4738698913;
echo $a ^= 43814;  

?>

Expected result:
----------------
In Windows the result is -443704711
In Linux FC3 the result is -2147439834
