        * libgfortran.h (compile_options_t):  Add record_marker.
        * runtime/compile_options.c (set_record_marker):
        New function.
        * io/open.c:  If we have four-byte record markers, use
        GFC_INTEGER_4_HUGE as default record length.
        * io/file_pos.c (unformatted_backspace):  Handle
        different size record markers.
        * io/transfer.c (us_read):  Likewise.
        (us_write):  Likewise.
        (next_record_r):  Likewise.
        (write_us_marker):  Likewise.
        (next_record_w):  Likewise.
