    Do not compile code which might be unnecessary with GLib 2.35.9+
    
    This is the only relevant part of the code which should be "removed"
    from the previous commit due to changes in GNetworkManager's bug:
    https://bugzilla.gnome.org/show_bug.cgi?id=694181
    
    Once eds will depends on such GLib the conditioned code can be
    completely removed.
