Problem installing WordPress using MySQL5 and PHP5

I’ve setup many sites using PHP4 and MySQL4 but I’m now trying to set one up using PHP5 and MySQL5 but I get the following error message when trying to create the config file.

Error in my_thread_global_end(): 2 threads didn’t exit PHP Strict Standards: Declaration of Walker_Page::start_lvl() should be compatible with that of Walker::start_lvl() in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1229 PHP Strict Standards: Declaration of Walker_Page::end_lvl() should be compatible with that of Walker::end_lvl() in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1229 PHP Strict Standards: Declaration of Walker_Page::start_el() should be compatible with that of Walker::start_el() in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1229 PHP Strict Standards: Declaration of Walker_Page::end_el() should be compatible with that of Walker::end_el() in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1229 PHP Strict Standards: Declaration of Walker_PageDropdown::start_el() should be compatible with that of Walker::start_el() in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1274 PHP Strict Standards: Declaration of Walker_Category::start_lvl() should be compatible with that of Walker::start_lvl() in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1421 PHP Strict Standards: Declaration of Walker_Category::end_lvl() should be compatible with that of Walker::end_lvl() in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1421 PHP Strict Standards: Declaration of Walker_Category::start_el() should be compatible with that of Walker::start_el() in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1421 PHP Strict Standards: Declaration of Walker_Category::end_el() should be compatible with that of Walker::end_el() in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1421 PHP Strict Standards: Declaration of Walker_CategoryDropdown::start_el() should be compatible with that of Walker::start_el() in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1472 PHP Strict Standards: Assigning the return value of new by reference is deprecated in F:\InetPub\Domains\cwac3.com\wwwroot\wp-includes\classes.php on line 1671

I’ve managed to get the site created but I keep getting the thread errors. Any ideas on how to stop the problem?
