[PHP] Error message

[Pete]

Hi List,

I am getting a strange error notice for the following config file:

<?php
/**
* Database
*/
$dsn = array(
    'phptype'  => 'mysql',
    'username' => 'root',
    'password' => 'secretpass',
    'hostspec' => 'localhost',
    'database' => 'mydb',
);

$options = 
array(
    'debug'       => 2,
    'portability' => DB_PORTABILITY_ALL,
);

/**
 * Language options
 */
$languages = array('de', 'en', 'it', 'fr', 'es', 'el', 'nl');
?>


 Notice: Use of undefined constant DB_PORTABILITY_ALL - assumed 'DB_PORTABILITY_ALL' 
in D:\utf8php5\config.php on line 16 

What can I do about this?

Thank you very much.
