compiling php with MySQL max 4.0.1 under windows

Hi, After I had succesfully compiled a snapshot from php, I noticed that accessing MySQL gave some errors. After looking at my phpinfo() I noticed that it said: "Client API version 3.23.39". I however are using MySQL 4.0.1-alpha, because of all the new features. I figured out that php obviously is using it's own source files to compile libmysql, instead of the ones of my own mysql version. In linux I could give the an extra paramter to ./configure like '--with-mysql=/path/to/mysql', but I'm using MSVC++ to compile my php and I have no idea how to set those options with that compiler. Does anyone have any idea how I can compile my php to make it compatible with MySQL 4.0.1? </Rense>
