Description:
------------
Comparing a string in the $_SERVER superglobal using the strict
equality operator (===) always fails, even though both types are
strings. $_GET and other variables work fine.

I'm using the php.ini-recommended file, with no changes except for
display_(startup_)errors which are enabled. My locale is sv_SE.UTF-8
(the LANG environment variable is set to this value)

This used to work fine in php6.0-200804260630

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

$rm = $_SERVER['REQUEST_METHOD'];
echo "Type is: ".gettype($rm)." <br />\n";
if (($rm !== 'GET') && ($rm == 'GET')) {
  echo "Bug! <br />\n";
} else {
  echo "Correct behaviour! <br />\n";
}


$sp = $_SERVER['SERVER_PROTOCOL'];
echo "Type is: ".gettype($sp)." <br />\n";
if (($sp !== 'HTTP/1.1') && ($sp == 'HTTP/1.1')) {
  echo "Bug! <br />\n";
} else {
  echo "Correct behaviour! <br />\n";
}


Expected result:
----------------
Type is: string
Correct behaviour! 
Type is: string
Correct behaviour! 


Actual result:
--------------
Type is: string
Bug!
Type is: string
Bug!
