32--  This package contains the search functions from Ada.Strings.Wide_Fixed.
33--  They are separated out because they are shared by Ada.Strings.Wide_Bounded
34--  and Ada.Strings.Wide_Unbounded, and we don't want to drag in other
35--  irrelevant stuff from Ada.Strings.Wide_Fixed when using the other two
36--  packages. We make this a private package, since user programs should
37--  access these subprograms via one of the standard string packages.
