/* Print a description of a type TYPE.

   If VARSTRING is a non-empty string, print as an Ada variable/field
       declaration.
   SHOW+1 is the maximum number of levels of internal type structure
      to show (this applies to record types, enumerated types, and
      array types).
   SHOW is the number of levels of internal type structure to show
      when there is a type name for the SHOWth deepest level (0th is
      outer level).
   When SHOW<0, no inner structure is shown.
   LEVEL indicates level of recursion (for nested definitions).  */
