Parse error, unexpected '&', expecting T_VARIABLE in pm_block_user.module on line 511

What the hug :)
See on drupal System requirements - http://drupal.org/requirements
Required: PHP version 4.3.5 or higher

You have "System requirements" for Privatemsg module?
And other...

Bug with PHP_INT_MAX fixed ( http://drupal.org/node/586468#comment-2250312 ) with next code pasted into the top of database.inc:

<?php

function get_int_max()
{
    $max=0x7fff;
    $probe = 0x7fffffff;
    while ($max == ($probe>>16))
    {
        $max = $probe;
        $probe = ($probe << 16) + 0xffff;
    }
    return $max;
}

if (!defined('PHP_INT_MAX'))
{
    define ('PHP_INT_MAX', get_int_max());
}
define ('PHP_INT_MIN', (int)(PHP_INT_MAX+1));
?>

And... If I fix bug with PHP_INT_MAX error, I have next error in pm_block_user module:

PHP Parse error:  parse error, unexpected '&', expecting T_VARIABLE or '$' in /indx/www
/gamezone2/sites/all/modules/privatemsg/pm_block_user/pm_block_user.module on line 511

What about that? :)

Patch work ok :)
Thank You!
