* 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
