Description:
------------
I want to work with DB bigint data type without troubles, I want to call mysql_insert_id() safely.

Also some problems in Google Code Jam require 8 bytes int and it's very hard to solve them with 4 bytes int because BC is too slow.

I know that this might be by design but it is a bad design. Especially given that Linux 64 bits builds have 8 bytes int.

Also the main advantage of 64 bits is to be able to use these 64 bits.


Test script:
---------------
<?php
echo PHP_INT_SIZE; // with php-5.5.0RC1-Win32-VC11-x64.zip


Expected result:
----------------
8

Actual result:
--------------
4
