Description:
------------
According to http://www.php.net/ZEND_CHANGES.txt,

"WIth both constants and functions, if you don't specify a class context the current class will be searched first and if the search fails then the global scope will be searched. If you want to force PHP to only check the global scope you can use the main:: accessor."

The snap I just downloaded seems to be search global first then the class second. Main:: doesn't seem to exist.

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

function asdf() {
   echo 'global';
}

class FooClass {
  function asdf() {
    echo 'class';
  }
  function printFoo() {
    asdf(); // outputs 'global'
    self::asdf(); // outputs 'class'
    main::asdf(); // Fatal error: Class 'main' not found in C:\Apache2\htdocs\test.php on line 14
  }
}
$qwerty = new FooClass;
$qwerty->printFoo();
?>

Expected result:
----------------
The first call to asdf() in printFoo should produce 'class'. The second self::asdf() seems to be correct, and the main::asdf() should print 'global'

Actual result:
--------------
The first call to asdf() in printFoo() should print 'class', not 'global'. The main:: accessor doesn't seem to be known but ZEND_CHANGES.txt says it does exist.
