from ChangeLog:
    - since Gtk::CList#remove conflict with Gtk::Continer#remove in name,
      rename it to Gtk::CList#remove_row as Gtk--.

Gtk+ core team has already admited that CList is broken from
design. so can't complain, i guess.

with X, it does.  You can't create Root window, but you can create
toplevel windows. dont' know about win32.
