        in several places.
        The grammar for the project files is now in each of the sections
        (packages,expressions,...) instead of being duplicates in two other

        the primitive operations of the type. This search must succeed
        regardless of visibility.

        * s-commun.adb (Last_Index): Count must be converted to SEO (a signed
