+-- OBJECTIVE:
+--      Check that a Size clause for an object is supported if the specified
+--      size is at least as large as the subtype's size, and correspond to a
+--      size in storage elements that is a multiple of the object's (non-zero)
+--      Alignment. RM 13.3(43)
+--
+-- TEST DESCRIPTION:
+--      This test defines several types and then asserts specific sizes for
+--      the, it then checks that the size set is reported back.
+--
+-- APPLICABILITY CRITERIA:
+--      All implementations must attempt to compile this test.
+--
+--      For implementations validating against Systems Programming Annex (C):
+--        this test must execute and report PASSED.
+--
+--      For implementations not validating against Annex C:
+--        this test may report compile time errors at one or more points
+--        indicated by "-- ANX-C RQMT", in which case it may be graded as inapplicable.
+--        Otherwise, the test must execute and report PASSED.
+--
+--
+-- CHANGE HISTORY:
+--      22 JUL 95   SAIC   Initial version
+--      08 MAY 96   SAIC   Corrected and strengthened for 2.1
+--      14 FEB 97   PWB.CTA Changed 'Size specifications to multiples
+--                         of System.Storage_Unit; restricted 'Size spec
+--                         for enumeration object to max integer size.
+--      16 FEB 98   EDS    Modify Documentation.
+--      25 JAN 99   RLB    Repaired to properly set and check sizes.
+--      29 JAN 99   RLB    Added Pack pragma needed for some implementations.
+--                         Corrected to support a Storage_Unit size < 8.
