Comment (by nacin):

 Replying to [comment:4 Otto42]:
 > Nacin: don't set the $engine variable there, set it in the wpdb class's
 constructor. If there's not one, make one. Then subclasses only get it if
 they call the parent constructor.

 Thanks for the idea. In that case, we should set it in db_connect(). That
 method is the first one which calls mysql_connect(). Anyone not using
 MySQL will *need* to override that (the constructor is a bit agnostic).
