/*
 * Unsolved problem: if a type is actually a pointer type, like
 * nid_triple is, then its impossible to get a const where you need
 * it. Consider:
 *
 * typedef int nid_triple[3];
 * const void *a_;
 * const nid_triple const *a = a_;
 *
 * The assignement discards a const because what you really want is:
 *
 * const int const * const *a = a_;
 *
 * But if you do that, you lose the fact that a is an array of 3 ints,
 * which breaks comparison functions.
 *
 * Thus we end up having to cast, sadly, or unpack the
 * declarations. Or, as I finally did in this case, delcare nid_triple
 * to be a struct, which it should have been in the first place.
 *
 * Ben, August 2008.
 *
 * Also, strictly speaking not all types need be const, but handling
 * the non-constness means a lot of complication, and in practice
 * comparison routines do always not touch their arguments.
