  73. * Unsolved problem: if a type is actually a pointer type, like
  74. * nid_triple is, then its impossible to get a const where you need
  75. * it. Consider:
  76. *
  77. * typedef int nid_triple[3];
  78. * const void *a_;
  79. * const nid_triple const *a = a_;
  80. *
  81. * The assignment discards a const because what you really want is:
  82. *
  83. * const int const * const *a = a_;
  84. *
  85. * But if you do that, you lose the fact that a is an array of 3 ints,
  86. * which breaks comparison functions.
  87. *
  88. * Thus we end up having to cast, sadly, or unpack the
  89. * declarations. Or, as I finally did in this case, declare nid_triple
  90. * to be a struct, which it should have been in the first place.
  91. *
  92. * Ben, August 2008.
  93. *
  94. * Also, strictly speaking not all types need be const, but handling
  95. * the non-constness means a lot of complication, and in practice
  96. * comparison routines do always not touch their arguments.
