        result type is class-wide and inherently limited, and the expression
        has a specific type, create a return object of the specific type, for
        more efficient handling of returns of build-in-place aggregates (avoids
        conversions of the class-wide return object to the specific type on
        component assignments).
 
        * sem_ch6.adb (Check_Return_Subtype_Indication): Suppress the error
        about a type mismatch for a class-wide function with a return object
        having a specific type when the object declaration doesn't come from
        source. Such an object can result from the expansion of a simple return.

        indirect call, report success to the caller to include possible
        interpretation.
 
        * sem_ch6.adb (Check_Return_Type_Indication): Apply proper conformance
        check when the type
        of the extended return is an anonymous access_to_subprogram type.
 
        * sem_res.adb:
        (Resolve_Call): Insert a dereference if the type of the subprogram is an
        access_to_subprogram and the context requires its return type, and a

        when switch -gnateG is used.

        Orig_Prev to Prev in the case where the actual is N_Function_Call or
        N_Identifier. This was interfering with other cases that are rewritten
        as N_Identifier, such as allocators, resulting in passing of the wrong
        accessibility level, and based on testing this code is apparently no

2008-08-01  Jose Ruiz  
 
        * adaint.c (__gnat_tmp_name): RTSS applications do not support tempnam

        type if the nominal type is a larger record.
        (gnat_to_gnu): Do not require integral modes on the source type to
        avoid the conversion for types with identical names.
        (addressable_p): Add gnu_type parameter.  If it is specified, do not
        return true if the expression is not addressable in gnu_type.
