Bug description:When containing a null character, $_GET variable not set
(properly)

When a null character is present in the value of a variable in the request
string (encoded as %00), said variable will either not be set in $_GET at
all (linux) or be set improperly (null character is escaped; win32)
Test script:
---------------
<?php
print_r($_GET);
if (isset($_GET['fb']))
{
echo strlen($_GET['fb']);
}
else
{
echo '<a href="?fb=foo%00bar">click me</a>';
}
Expected result:
----------------
After clicking the link:
Array
(
[fb] => foo�bar
)
7
Actual result:
--------------
After clicking the link:
- On a linux setup:
Array
(
)
<a href="?fb=foo%00bar">click me</a>
- On a win32 setup:
Array
(
[fb] => foo\0bar
)
