* ch-valprint.c (calculate_array_length): New function to determine

        the length of an array type (see comment).
        (chill_val_print (case TYPE_CODE_ARRAY)): If the length of an
        array type is zero, call calculate_array_length.

        * gdbtypes.c (get_discrete_bounds (case TYPE_CODE_ENUM)): They values
        may not be sorted. Scan all entries and set the real lower and

+/* In certain cases it could happen, that an array type doesn't
+   have a length (this have to do with seizing). The reason is

+   .stabs "m_x:Tt81=s36i:1,0,32;ar:82=ar80;0;1;83=xsm_struct:,32,256;;",128,0,25,0

+
+   When processing t81, the array ar80 doesn't have a length, cause
+   struct m_struct is specified extern at thse moment. Afterwards m_struct
+   gets specified and updated, but not the surrounding type.
+
+   So we walk through array's till we find a type with a length and
+   calculate the array length.
