        PR libgfortran/30162
        * io/unix.c (fd_flush): Don't seek if file is not seekable, defined as
        s->file_length == -1.
        (fd_alloc_w_at): Do not adjust file_length if file is not seekable.
        (fd_seek): If not seekable, just return success.
        (fd_truncate): If not seekable, no need to truncate.  Return failure if
        seek fails and the stream is not a pipe.
        (fd_to_stream): Make test for non-seekable file more robust.
