Issues aside, and arguably this is personal taste, etc., but I think
the premise of the patch is questionable. I.e., I don't think
replacing

    wine_rb_destroy( &wine_drivers, wine_drivers_rb_destroy, NULL );

with

    WINE_RB_FOR_EACH_ENTRY_DESTRUCTOR( driver, next, &wine_drivers,
struct wine_driver, entry )

is an improvement to begin with.
