        to the same class-wide type.
        (Default_Iterator): An iterator defined by an aspect of some
        container type T must have a first parameter of type T, T'class,

        a C type supported by the back-end and suitable as a basis to
        construct the standard Ada floating point type identified by
        the T parameter. This is used as a common ground to feed both
        ttypes values and the GNAT tree nodes for the standard floating
        point types.
        * set_targ.adb (Long_Double_Index): The index at which "long
        double" gets registered in the FPT_Mode_Table. This is useful to
        know whether we have a "long double" available at all and get at
        it's characteristics without having to search the FPT_Mode_Table
        when we need to decide which C type should be used as the
        basis for Long_Long_Float in Ada.
        (Register_Float_Type): Fill Long_Double_Index.
        (FPT_Mode_Index_For): New function. Return the index in

        FPT_Mode_Table that designates the entry for a back-end type
        suitable as a basis to construct the standard Ada floating point
        type identified by the input T parameter.
        (elaboration code): Register_Back_End_Types unconditionally,
        so C_Type_For can operate regardless of -gnateT. Do it
        early so we can query it for the floating point sizes, via
        FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
        Long_Double_Size from the FPT_Mode_Table, as cstand will do.
        * cstand.adb (Create_Float_Types): Use C_Type_For to determine
        which C type should be used as the basis for the construction
        of the Standard Ada floating point types.

        build function and operator wrappers after the actual subprogram
        has been resolved, and replace the standard renaming declaration
        with the declaration of wrapper.
        * sem_ch12.ads (Build_Function_Wrapper, Build_Operator_Wraooer):
        make public for use elsewhere.
        * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):
        rewrite, now that actual is fully resolved when wrapper is
        constructed.
