- No more nesting of Module and Module Type, we rather use Include.
- Instead of in-name-qualification like NZeq, we use uniform
short names + modular qualification like N.eq when necessary.
- Many simplification of proofs, by some autorewrite for instance
- In NZOrder, we instantiate an "order" tactic.
- Some requirements in NZAxioms were superfluous: compatibility
of le, min and max could be derived from the rest.
- NMul removed, since it was containing only an ad-hoc result for
ZNatPairs, that we've inlined in the proof of mul_wd there.
- Zdomain removed (was already not compiled), idea of a module
with eq and eqb reused in DecidableType.BooleanEqualityType.
- ZBinDefs don't contain any definition now, migrate it to ZBinary.

- NStrongRec provides a "strong" recursor based on the usual one:
recursive calls can be done here on any lower value.
See binary log in NDefOps for an example of use.
- NDefOps contains alternative definitions of usual operators
(add, mul, ltb, pow, even, half, log)
via usual or strong recursor, and proofs of correctness and/or
of equivalence with axiomatized operators.
These files were in the archive but not being compiled,
some proofs of correction for functions defined there were missing.
By the way, some more iff-style lemmas in Bool.

This way we get properties of Rmin / Rmax (almost) for free.
TODO: merge Rbasic_fun and Rminmax...

- A richer OrderedTypeFull interface : OrderedType + predicate "le"
- Implementations {Nat,N,P,Z,Q}OrderedType.v, also providing "order" tactics
- By the way: as suggested by S. Lescuyer, specification of compare is
now inductive
- GenericMinMax: axiomatisation + properties of min and max out of
OrderedTypeFull structures.
- MinMax.v, {Z,P,N,Q}minmax.v are specialization of GenericMinMax,
with also some domain-specific results, and compatibility layer
with already existing results.
- Some ML code of plugins had to be adapted, otherwise wrong "eq",
"lt" or simimlar constants were found by functions like coq_constant.
- Beware of the aliasing problems: for instance eq:=@eq t instead of
eq:=@eq M.t in Make_UDT made (r)omega stopped working (Z_as_OT.t
instead of Z in statement of Zmax_spec).
- Some Morphism declaration are now ambiguous: switch to new syntax
anyway.
- Misc adaptations of FSets/MSets
- Classes/RelationPairs.v: from two relations over A and B, we
inspect relations over A*B and their properties in terms of classes.

Thanks to the functors in FSetCompat, the three implementations
of FSets (FSetWeakList, FSetList, FSetAVL) are just made of a few
lines adapting the corresponding MSets implementation to the old
interface.
This approach breaks FSetFullAVL. Since this file is of little use
for stdlib users, we migrate it into contrib Orsay/FSets.

This file contains low-level stuff for FSets/FMaps. Switching it to
the new version (the one using Equivalence and so on instead of
eq_refl/eq_sym/eq_trans and so on) only leads to a few changes in
FSets/FMaps that are minor and probably invisible to standard users.

FSets, and improve it
As soon as you have a eq, a lt and a le (that may be lt\/eq, or (complement (flip (lt)))
and a few basic properties over them, you can instantiate functor MakeOrderTac
and gain an "order" tactic. See comments in the file for the scope of this tactic.
NB: order doesn't call auto anymore. It only searches for a contradiction in the
current set of (in)equalities (after the goal was optionally turned into hyp
by double negation). Thanks to S. Lescuyer for his suggestions about this tactic.

Same global ideas (in particular the use of modules/functors), but:
- frequent use of Type Classes inside interfaces/implementation.
For instance, no more eq_refl/eq_sym/eq_trans, but Equivalence.
A class StrictOrder for lt in OrderedType. Extensive use of Proper
and rewrite.
- now that rewrite is mature, we write specifications of set operators
via iff instead of many separate requirements based on ->. For instance
add_spec : In y (add x s) <-> E.eq y x \/ In x s.
Old-style specs are available in the functor Facts.
- compare is now a pure function (t -> t -> comparison) instead of
returning a dependent type Compare.
- The "Raw" functors (the ones dealing with e.g. list with no
sortedness proofs yet, but morally sorted when operating on them)
are given proper interfaces and a generic functor allows to obtain
a regular set implementation out of a "raw" one.
The last two points allow to manipulate set objects that are completely free
of proof-parts if one wants to. Later proofs will rely on type-classes
instance search mechanism.
No need to emphasis the fact that this new version is severely incompatible
with the earlier one. I've no precise ideas yet on how allowing an easy
transition (functors ?). For the moment, these new Sets are placed alongside
the old ones, in directory MSets (M for Modular, to constrast with forthcoming
CSets, see below). A few files exist currently in version foo.v and foo2.v,
I'll try to merge them without breaking things. Old FSets will probably move
to a contrib later.
Still to be done:
- adapt FMap in the same way
- integrate misc stuff like multisets or the map function
- CSets, i.e. Sets based on Type Classes : Integration of code contributed by
S. Lescuyer is on the way.

* Import of Coq_config via myocamlbuild_config.ml, instead of my get_env
* As a consequence, we enrich this Coq_config with stuff that was
only in config/Makefile
* replace the big ugly find by some dependencies against source files
* by the way: build csdpcert, with the right aliases.
I've tried to escape things properly for windows in ./configure,
but this isn't fully tested yet.
