Changement dans le kernel :

   - essai de suppression des dependances debiles. (echec) 
   - Application des patch debian.

Pour ring et field :
   - introduciton de la function de sign et de puissance.
   - Correction de certains bug.
   - supression de ring_replace ....

Pour exact_no_check :
   - ajout de la tactic : vm_cast_no_check (t)
     qui remplace "exact_no_check (t<: type of Goal)"
      (cette version forcais l'evaluation du cast dans le 
       pretypage).
