Must have been sleep deprived when I looked at this last.

The only problem is the value we use for the max unsigned range. It
should be changed to allow - 2^31, but I did not check the code more in
details, but Ilia is on it so :)

We don't eat a 0. When parsing #s we follow this logic:

Let's say X is our temp var containing the 1st digit and the number to

be parsed is 435.

X = X * 10;
X += 3; (X = 43)

X = X * 10;
X += 5; (X = 435)

There is no 0 eating etc...

For some reason php_filter_parse_int multiplies the integer by ten then
attempts to eat a 0? This is causing overflow and resulting in an
error.

I have no idea why its doing this though. ilia?

Description:
------------
Although -2147483648 is the minimum integer in 32bit environment, 
FILTER_VALIDATE_INT says -2147483648 is invalid as integer.

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

var_dump(intval("-2147483648"));
var_dump(filter_var("-2147483648", FILTER_VALIDATE_INT));

Expected result:
----------------
int(-2147483648)
int(-2147483648)

Actual result:
--------------
int(-2147483648)
bool(false)
