        analyzer.
        * sem_ch13.adb (Build_Predicate_Function): Change calling sequence, and
        change the order in which things are done to fix several errors in

        The timestamp is now retreived using GetFileAttributesEx as faster.

        (Derive_Subprograms): For abstract private types transfer to the full
        view entities of uncovered interface primitives. Required because if
        the interface primitives are left in the private part of the package
        they will be decorated as hidden when the analysis of the enclosing
        package completes (and hence the interface primitive is not visible

        type as a whole, or when the type is derived and it has an inherited

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

        frozen.

        type, done in an arbitrary, possibly incorrect type (the presence of
        some numeric type in the scope is checked for legality, but when more

        necessarily the expected one).

        * sem_aggr.adb (Resolve_Array_Aggregate): Check for the case where this
        is an internally-generated positional aggregate, and the bounds are
        already correctly set. We don't want to overwrite those bounds with
        bounds determined by context.

        * s-commun.adb (Last_Index): Count must be converted to SEO (a signed
        integer type) before subtracting 1, otherwise the computation may wrap
        (because size_t is modular) and cause the conversion to fail.
