/*-

[85] Fix | Delete

* Unsolved problem: if a type is actually a pointer type, like

[86] Fix | Delete

* nid_triple is, then its impossible to get a const where you need

[87] Fix | Delete

* it. Consider:

[88] Fix | Delete

[89] Fix | Delete

* typedef int nid_triple[3];

[90] Fix | Delete

* const void *a_;

[91] Fix | Delete

* const nid_triple const *a = a_;

[92] Fix | Delete

[93] Fix | Delete

* The assignment discards a const because what you really want is:

[94] Fix | Delete

[95] Fix | Delete

* const int const * const *a = a_;

[96] Fix | Delete

[97] Fix | Delete

* But if you do that, you lose the fact that a is an array of 3 ints,

[98] Fix | Delete

* which breaks comparison functions.

[99] Fix | Delete

[100] Fix | Delete

* Thus we end up having to cast, sadly, or unpack the

[101] Fix | Delete

* declarations. Or, as I finally did in this case, declare nid_triple

[102] Fix | Delete

* to be a struct, which it should have been in the first place.

[103] Fix | Delete

[104] Fix | Delete

* Ben, August 2008.

[105] Fix | Delete

[106] Fix | Delete

* Also, strictly speaking not all types need be const, but handling

[107] Fix | Delete

* the non-constness means a lot of complication, and in practice

[108] Fix | Delete

* comparison routines do always not touch their arguments.
