/*-
* 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 assignment 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, declare 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.
