Description:
------------
Up to PHP 5.5.9 gmp_init() called with an empty string as argument had the same result as called with a zero. In PHP 5.6 Alpha 1 (and the current snapshot) this call throws a warning. This breaks existing code.
Test script:
---------------
echo gmp_strval(gmp_init(''));
Expected result:
----------------
"0"
Actual result:
--------------
Warning: gmp_init() [function.gmp-init.php]: Unable to convert variable to GMP - string is not an integer in /SPACE/ww3/www/wws/130009.php(103) : eval()'d code on line 1
"0"

gmp_init('') did not return a GMP zero, but boolean false, indicating an error condition. PHP 5.6 adds a warning for that previously silent error.
