Perhaps the next step should be to create "gtk12" and "gtk2"
subdirectories and move stuff that has lots of #ifdefs there, and leave
the rest of the stuff in "gtk".  For routines that are mostly the same,
perhaps helper routines or macros could be put in "gtk12" and "gtk2",
with the stuff in "gtk" calling it (e.g.:

    gtk12:

	#define SIGNAL_CONNECT(widget, name, callback, arg) \
		gtk_signal_connect(GTK_OBJECT(widget), name, \
                     GTK_SIGNAL_FUNC(callback), \
		     (arg) == NULL ? NULL : GTK_OBJECT(arg));

    gtk2:

	#define SIGNAL_CONNECT(widget, name, callback, arg) \
		g_signal_connect(G_OBJECT(widget), name, \
                   G_CALLBACK(callback), \
                   (arg) == NULL ? NULL : G_OBJECT(arg));
