    Fix issue in sending a boolean created from a pointer in
    Fix from Richard Kreuter.  This makes his clm-young::chooseone demo
    work reliably.  Richard writes:
        The detail that this patch affects is non-deterministic:
        RXmStringGetLtoR in xmstring.c calls message_write_boolean on a
        pointer, message_write_boolean in datatrans.c calls
        combine_type_and_data with the pointer and the boolean type tag,
        and combine_type_and_data in datatrans.h IORs the boolean type tag
        with the bits 25 to 32 from the start of the pointer.
        This gave a decoding error on the Lisp side in TOOLKIT-READ-VALUE,
        because the high 8 bits of the 32 bits being decoded indexed past
        the end of *TYPE-TABLE*. (But other incorrect outcomes are
        possible, e.g., the result of combine_type_and_data could index a
        valid, but wrong, type code, etc.)
