  33 --  They are separated because Ada.Strings.Wide_Wide_Bounded shares these
  34 --  search functions with Ada.Strings.Wide_Wide_Unbounded, and we don't want
  35 --  to drag other irrelevant stuff from Ada.Strings.Wide_Wide_Fixed when using
  36 --  the other two packages. We make this a private package, since user
  37 --  programs should access these subprograms via one of the standard string
