PHP6 WIndows Builds

Please Is there any way to get a full windows build of the PHP6 since I don't have the tools to do it myself. In particular I need the php_interbase module which is missing from the previously kindly posted build ( and the pdo_firebird if I'm to keep and eye on that ;) ) It has been decided that our production systems will stay with PHP5.0.4 since everything is stable ( and none of them are accessible outside the sites they are installed so no security problems ) and switch the development environment to PHP6 and start testing that :)
