the easiest way is probably to wrap the call like so:

static void
my_handler (GtkToggleButton *tb)
{
  gtk_signal_handler_block_by_func (GTK_OBJECT (tb), GTK_SIGNAL_FUNC (my_handler), NULL);
  gtk_toggle_button_set_state (tb, !tb->active);
  gtk_signal_handler_unblock_by_func (GTK_OBJECT (tb), GTK_SIGNAL_FUNC (my_handler), NULL);
}
