  It is not optional because it is designed to use it.  Also I do not
  think adding libidn by default is a big problem for most of people
  because ghostscript9 already depends on 47 packages and libidn is
  small enough.  Adding a knob increases the maintenance cost---it is
  not small as you expect.  These are the reasons why I have no
  intention to add it at this moment unless it has a problem about the
  functionality or huge bloat of the dependency.
