note 46426 added to install.windows.extensions

I have a PHP 5.0.1 installation on an Apache 2.0.51 server under Windows XP. When I try to enable the MySQL extension, I get this error message: [11-Oct-2004 01:42:58] PHP Warning: PHP Startup: mysql: Unable to initialize module Module compiled with module API=20040412, debug=0, thread-safety=1 PHP compiled with module API=20040316, debug=0, thread-safety=1 These options need to match in Unknown on line 0 How can I fix this?
