note 50437 added to install.windows.extensions

I'v done every setting in extensions_dir. The directory is correctly set to "f:\php\ext". But when I restart Apache server, it still doesn't work. It tell me a warning: "PHP Startup: Unable to load dynamic library "f:\php\ext\php_mysql.dll", But the file is really there.
