* ch-valprint.c (chill_val_print): Remove call to calculate_array_length.

        (calculate_array_length): Move function from here ...

        * ch-exp.c (calculate_array_length): ... to here.
        (parse_primval): If we have a symbol with an array type
        and the length is 0, call calculate_array_length.

+   When processing t81, the array ar80 doesn't have a length, cause
+   struct m_struct is specified extern at thse moment. Afterwards m_struct
