        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
        sections (one in the user's guide that contained the full grammar,

        grammar).

        were incomplete
        Rename "associative array" into "indexed attribute"
        Remove sections that were duplicates ("External References in
        Project Files" and "External Values", and "Project Extensions"
        for instance). The list of valid packages in project files is now in
        a single place.

        * sem_ch3.adb (Add_Internal_Interface_Entities): If
        Find_Primitive_Covering_Interface does not find the operation, it may
        be because of a name conflict between the inherited operation and a
        local non-overloadable name. In that case look for the operation among
        the primitive operations of the type. This search must succeed
        regardless of visibility.

        name is a call, use the number of actuals to determine whether this is
        a binary or unary operator, rather than relying on later information
        to resolve the overload.

        procedure, to handle quietly identifiers that have no entity names.
        * exp_util.adb (Get_Current_Value_Condition): If the parent of an
        elsif_part is missing, it has been rewritten as a nested if, and there
