(suppression au passage d'un cast dans constant_entry_of_com - ce
n'est pas normal qu'on force le type s'il n'est pas déjà présent mais
en même temps il semble que ce cast serve pour rafraîchir les univers
algébriques...)

to accept a mind_specif (a couple mutual_inductive_body * one_inductive_body)
instead of looking it up in the environment. A version of the same functions
with the old type is put in Inductiveops (outside the kernel).

MOVITATION: in a forthcoming commit the application of a substitution to a
constant will return a constr and not a constant. The application of a
substitution to a kernel_name will return a kernel_name. Thus "constant"
should be use as a kernel name for references that can be delta-expanded.
KNOWN PROBLEMS: the only problem faced is in pretyping/recordops.ml (the code
that implements "Canonical Structure"s). The ADT is violated once in this
ocaml module. My feeling is that the implementation of "Canonical Structure"s
should be rewritten to avoid this situation.

to decide whether a conversion should be generated (exporting both types).
The comparison function used is Coq alpha conversion, that is also up to
Casts. When it was successful, the only type that was kept was the synthesized
one.
In several CoRN theorems it happened that the expected type carried a few
casts to make subterms of it be of type/sort CProp (instead of Type).
These casts were forgot, and the innersort computed was imprecise.
This partial fix consists in keeping the expected type. However, it may
happen (at least in theory) that the casts to CProp are part of the
synthesized type and not of the expected type. In this case they will be
lost anyway. Properly fixing the problem would mean recur over the two
alpha-convertible terms to add the casts from both sources. However, this
operation is very expensive and I would prefer to avoid it.

type inference for inferred types) undone. Previous performance restored.
- bug in cic2acic (code that used to be dead fixed): the type of a sort
was computed as the sort itself
- CPropRetyping in cic2acic modified to handle correctly the sort Set in
the two cases Predicative Set / Impredicative Set
- CPropRetyping.get_type_of used in place of Retyping.get_type_of everywhere
in cic2acic. This closes (again, but more efficiently) the bug about
CProps erroneously recognized as Types in inferred types

* Motivation: the inner sorts computed for the inner types were computed
by Coq itself. Thus Nijmegen's CProp was exported as Type. To export CProp
as CProp I have to implement a CProp-aware single type inference.
To avoid the reimplementation I use double type inference.
* Known problems: the double type inference algorithm is slower than the
usual type inference algorithm. Moreover too many types and sorts are
computed in this way. As a consequence the exportation module is now
much slower (the exportation time seems to be doubled in the average
case).
In the future I will try to restore the original performances.
