Support for Microsoft's Native SQL Server Driver for PHP - Patch by Chris Pucci at Microsoft [Bug #57055]

Browse Source 
If you are using SQL Server, please try to test this new dbal so we can safely include it in 3.0.8. If you
want to try it on a current phpBB version you can apply the latest version of the patch to your board which
you can find attached to the bug tracker ticket (look in the comments for the latest version, the one in the
ticket itself is outdated): http://www.phpbb.com/bugs/phpbb3/ticket.php?ticket_id=57055
