the php function filesize  (and probably others) are affected by a integer overflow problem

if a file of 2147483649 bytes (that exceeds integer_max_value and make integer become negative) is passed to filsize(); it return negative values.

Reproduce code:

Expected result:
get the REAL filesize

incorrect filesize
