Description:
------------
PHP manual at http://ch2.php.net/manual/en/function.gmp-div-r.php claims 
for gmp_div_r:

-----
resource gmp_div_r ( resource $n , resource $d [, int $round ] )
Calculates remainder of the integer division of n by d . The remainder 
has the sign of the n argument, if not zero.
-----

However,

print(gmp_strval(gmp_div_r(-5, 100)) . "\n");

Will result in "5", not "-5".

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

print(gmp_strval(gmp_div_r(-5, 100)) . "\n");

?>

Expected result:
----------------
-5

Actual result:
--------------
5
