* m68k/tm-delta68.h (CPLUS_MARKER): Macro deleted.
        (EXTRACT_STRUCT_VALUE_ADDRESS): Macro defined.
        (EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE): Macros modified
        because floating-point values return via %fp0.
        (CLEAR_INSN_CACHE): New macro.
        * m68k/tm-m68k.h (REGISTER_CONVERT_TO_VIRTUAL): Macro fixed
        to use DOUBLEST.
        (REGISTER_CONVERT_TO_RAW): Ditto.
        * infptrace.c (child_xfer_memory): If CLEAR_INSN_CACHE is defined,
        call it after having written in child process's memory.
        * inflow.c (PROCESS_GROUP_TYPE): Macro defined if HAVE_TERMIO.
        (gdb_has_a_terminal, terminal_ours_1): Functions fixed for HAVE_TERMIO.
