libgnomeui using deprecated GTK+ APIs in its own API

[Federico Mena Quintero <federico ximian com>]

Hello,

Libgnomeui has a few interesting spots where it exposes deprecated GTK+
APIs in its own API.  For example,

void
gnome_client_request_interaction_interp (GnomeClient *client,
					 GnomeDialogType dialog_type,
					 GtkCallbackMarshal function,
					 gpointer data,
					 GtkDestroyNotify destroy);

The _interp set of functions is likely to be highly obsolete because
GTK+ 2.0 completely changed the type system and thus the way it is
supposed to integrate with language bindings.

So, what should we do here?  Surround these prototypes with #ifndef
LIBGNOMEUI_DISABLE_DEPRECATED or something like that, or convert them to
GClosure and friends and thus breaking code that uses them?

[Is there a master plan for language bindings that I can read somewhere?]
