* calls.c (emit_call_1): Wrap varaible `struct_value_size_rtx' in

        macro conditionals guarding use.

        * dwarf2out.c: Include "tm_p.h".

        * function.c (locate_and_pad_parm): Mark parameter with
        ATTRIBUTE_UNUSED.
        (expand_function_end): Likewise for variable `context'.

        * reorg.c (make_return_insns): Wrap prototype in macro HAVE_return.

cp:
        * call.c: If GATHER_STATISTICS, declare `n_build_method_call'.
