Description:
------------
This is not a bug in php itself, but the error message is confusing.

It tells me to make class bie abstract.

Where I think it should tell me I should implement method b.

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

interface a {
    public function b();
}

class bie implements a { }

new bie;

?>

Expected result:
----------------
Fatal error: Class bie contains 1 abstract methods and must therefore be declared abstract (a::b)

Actual result:
--------------
Fatal error: Class bie should implement method b from interface a in /usr/src/test.php on line 16

or something like that.
