[gtkmm] Build error using jhbuild

[Marcus Brubaker <mbrubake cs toronto edu>]

Using jhbuild to build gtkmm/glibmm from CVS I keep running into the
following compile errors:

widget.cc: In member function `void
Gtk::Widget::unset_fg(Gtk::StateType)':
widget.cc:243: invalid static_cast from type `Gtk::StateType' to type
   `GtkStateType'
widget.cc: In member function `void
Gtk::Widget::unset_bg(Gtk::StateType)':
widget.cc:248: invalid static_cast from type `Gtk::StateType' to type
   `GtkStateType'
widget.cc: In member function `void
Gtk::Widget::unset_text(Gtk::StateType)':
widget.cc:253: invalid static_cast from type `Gtk::StateType' to type
   `GtkStateType'
widget.cc: In member function `void
Gtk::Widget::unset_base(Gtk::StateType)':
widget.cc:258: invalid static_cast from type `Gtk::StateType' to type
   `GtkStateType'


Anyone know how I might be able to fix these?  I am using an (older)
version of gcc if that matters.  g++ --version sayes its 3.0.2.  Thanks.
