I don't have any Linux system available to build and test. The bug is
visible on a hosting. Can you get someone else to test?
BTW I forgot my pswd and mails on forgotten pswd do not come through.

Description:
------------
If big negative number (-3032250090012579) is converted to integer, php
5.1.6 does not overflow on LINUX and uses max negative integer value
(-2147483648) instead. Though on Windows it works as ok. Related bug
#30315.


Reproduce code:
---------------
$a2 = 2224955379988029;
echo "$a2 => (int)" . (int)$a2 . "\n";
$a3 = -2224955379988029;
echo "$a3 => (int)" . (int)$a3 . "\n";


Expected result:
----------------
2.224955379988E+015 => (int)-888097219
-2.224955379988E+015 => (int)888097219


Actual result:
--------------
2.22495537999E+15 => (int)-888097219
-2.22495537999E+15 => (int)-2147483648
