-- OBJECTIVE:

--     CHECK THAT A RECORD REPRESENTATION CLAUSE CAN BE GIVEN FOR

--     A DERIVED SUBTYPE WHOSE PARENT TYPE IS A RECORD TYPE WITH

--     VARIANTS AND THE REPRESENTATION CLAUSE MENTIONS COMPONENTS THAT

--     DO NOT EXIST IN THE DERIVED SUBTYPE.

-- HISTORY:

--     RJW 08/25/87  CREATED ORIGINAL TEST.

--     DHH 03/27/89  CHANGED EXTENSION FROM '.DEP' TO '.ADA' AND

--                   ADDED CHECK FOR REPRESENTATION CLAUSE.

--     RJW 10/26/89  REMOVED REFERENCES TO LENGTH_CHECK.

--     THS 09/18/90  MADE CALLS TO IDENT_INT TO DEFEAT OPTIMIZATION.

--     JRL 10/13/96  Adjusted ranges in type definitions to allow 1's

--                   complement machines to represent all values in

--                   the specified number of bits.
