  * In hat-trans, if a module has no export list, produce an export list
  containing only the stuff that should be exported.  This avoids the
  problem of overlapping definitions of internally-generated identifiers
  (e.g. source positions) in a multi-module program.  A little bit of
  a hack but should work.
  
  (Also noticed that a default declaration should always be deleted by
  the transformation).
