--with-mysqli and --with-mysql

Howdy list, http://us2.php.net/manual/en/ref.mysqli.php under "Installation" is says: "If you would like to install the mysql extension along with the mysqli extension you have to use the same client library to avoid any conflicts." So, assuming PHP5 and MySQL > 4.1.3: These are the two ways to do both --with-mysql and --with-mysqli correct:

 a) --with-mysql      --with-mysqli=/path/to/mysql_config

b) --with-mysql=/usr --with-mysqli=/usr If not, whats the proper way to do --with-mysqli with: a) -with-mysql b) --with-mysql=DIR I asked php-db@lists.php.net but was met with crickets :) TIA!
