Description:
------------
I just experiment this behavior with PHP5.4a3 when running the following code:
    <?php
    abstract class Zend_Pdf_FileParserDataSource
    {
        abstract public function __construct();
    }

    class Zend_Pdf_FileParserDataSource_File extends Zend_Pdf_FileParserDataSource
    {
        public function __construct($filePath)
        {}
    }

    $test = new Zend_Pdf_FileParserDataSource_File('path');

    // Throw a Fatal Error:
    /*
    PHP Fatal error: Declaration of Zend_Pdf_FileParserDataSource_File::__construct() must be compatible with that of Zend_Pdf_FileParserDataSource::__construct() in /home/mikaelkael/php54.php on line 11

    Fatal error: Declaration of Zend_Pdf_FileParserDataSource_File::__construct() must be compatible with that of Zend_Pdf_FileParserDataSource::__construct() in /home/mikaelkael/php54.php on line 11
   */

It throws a fatal error (like a "normal" class method in 5.3). But this code was OK for the constructor in 5.3. In case of new behavior, is it possible to document it? I can't find any informations in NEWS or in UPGRADE files.

Test script:
---------------
<?php
abstract class Zend_Pdf_FileParserDataSource
{
    abstract public function __construct();
}

class Zend_Pdf_FileParserDataSource_File extends Zend_Pdf_FileParserDataSource
{
    public function __construct($filePath)
    {}
}

$test = new Zend_Pdf_FileParserDataSource_File('path');

// Throw a Fatal Error:
/*
