26-- OBJECTIVE:
27--      Check that the functionality found in packages Ada.Strings.Wide_Maps,
28--      Ada.Strings.Wide_Unbounded, and Ada.Strings.Wide_Maps.Wide_Constants
29--      is available and produces correct results.

31-- TEST DESCRIPTION:
32--      This test tests the subprograms found in the
33--      Ada.Strings.Wide_Unbounded package.  It is based on the tests
34--      CXA4030-32, which are tests for the complementary "non-wide"
35--      packages.
36--
37--      The functions found in CXA4033_0 provide mapping capability, when
38--      used in conjunction with Wide_Character_Mapping_Function objects.
