Description:
------------
get_browser() returns false when given valid parameters.  browscap.ini is the latest downloaded from http://www.garykeith.com/browsers/downloads.asp

browscap is set correctly in php.ini and shows in phpinfo()

Reproduce code:
---------------
echo count(file(ini_get('browscap')))."<br><br>";

$browser = get_browser('Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3', true);

var_dump($browser);

The first line shows that the browscap.ini file is being read properly

# wc -l /php5/lib/browscap.ini
14296 /php5/lib/browscap.ini


Expected result:
----------------
14296
