Actually Emacs has used GtkFileChooser by default for a long time now, more or 
less since it became available in a stable Gtk+ release.  But if both are 
available, GtkFileSelection can be used (I don't remember the customize 
variable for it right now).  There is a configure test for both file dialogs, 
so if one is removed in 3.0, Emacs will compile just fine.  However, as 
configure just looks at link time symbols, we might not do the right thing 
when compiled with -DGTK_DISABLE_DEPRECATED.  I'll check this.
