See now https://github.com/coq/bignums
Int31 is still in the stdlib.
Some proofs there has be adapted to avoid the need for BigNumPrelude.

CompareSpec expects 3 propositions Peq Plt Pgt instead of 2 relations
eq lt and 2 points x y. For the moment, we still always use (Peq=eq x y),
(Plt=lt x y) (Pgt=lt y x), but this may not be always the case,
especially for Pgt. The former CompSpec is now defined in term of
CompareSpec. Compatibility is preserved (except maybe a rare unfold
or red to break the CompSpec definition).
Typically, CompareSpec looks nicer when we have infix notations, e.g.
forall x y, CompareSpec (x=y) (x<y) (y<x) (x?=x)
while CompSpec is shorter when we directly refer to predicates:
forall x y, CompSpec eq lt x y (compare x y)

conversion when checking types of instanciations while having
restricted delta reduction for unification itself. This
makes auto/eauto... backward compatible.
- Change semantics of [Instance foo : C a.] to _not_ search
for an instance of [C a] automatically and potentially slow
down interaction, except for trivial classes with no fields.
Use [C a := _.] or [C a := {}] to search for an instance of
the class or for every field.
- Correct treatment of transparency information for classes
declared in sections.

To avoid names¬ations clashs with list, Vector shouldn't be
"Import"ed but one can "Import Vector.VectorNotations." to have
notations.
SetoidVector at least remains to do.

- Many of them were broken, some of them after Pierre B's rework
of mli for ocamldoc, but not only (many bad annotation, many files
with no svn property about Id, etc)
- Useless for those of us that work with git-svn (and a fortiori
in a forthcoming git-only setting)
- Even in svn, they seem to be of little interest

- ring/field: detection of constants for ring/field,
detection of power, potential use of euclidean division.
- for BigN and BigZ, x^n now takes a N as 2nd arg instead of a positive
- mention that we can use (r)omega thanks to (ugly) BigN.zify, BigZ.zify.
By the way, BigN.zify could still be improved (no insertion of positivity
hyps yet, unlike the original zify).
- debug of BigQ.qify (autorewrite was looping on spec_0).
- for BigQ, start of a generic functor of properties QProperties.
- BigQ now implements OrderedType, TotalOrder, and contains facts
about min and max.

We use the <+ operation to regroup all known facts about BigN
(resp BigZ, ...) in a unique module. This uses also the new ! feature
for controling inlining. By the way, we also make sure that these
new BigN and BigZ modules implements OrderedTypeFull and TotalOrder,
and also contains facts about min and max (cf. GenericMinMax).
Side effects:
- In NSig and ZSig, specification of compare and eq_bool is now
done with respect to Zcompare and Zeq_bool, as for other ops.
The order <= and < are also defined via Zle and Zlt, instead
of using compare. Min and max are axiomatized instead of being
macros.
- Some proofs rework in QMake
- QOrderedType and Qminmax were in fact not compiled by make world
Still todo: OrderedType + MinMax for BigQ, etc etc

* keep only one implementation of BigQ
* QMake (ex-Q0Make) becomes functorial
* proofs in it have been reworked, some new functions (e.g. red, power)
* BigQ.t is declared to be a setoid and a field
