* m68k/tm-delta68.h (EXTRACT_RETURN_VALUE): Type argument for
        `REGISTER_CONVERT_TO_VIRTUAL is `TYPE', not
        `REGISTER_VIRTUAL_TYPE (FP0_REGNUM)';
        (STORE_RETURN_VALUE): Ditto, and offset for `write_register_bytes'
        is `REGISTER_BYTE (FP0_REGNUM)', not `FP0_REGNUM'.
        (FRAME_NUM_ARGS): New macro.
        * m68k/tm-news.h (EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE): Ditto.
        * delta68-nat.c (clear_insn_cache): New function, forgotten in previous
        patch.
