/* Some functions are used by the stub resolver implementation
   internally and thus have to be located in libc.  They have been
   historially exported for application use as well.  However, the
   stub resolver dependency on those functions is not intrinsic to
   what the stub resolver does, and it is possible that a future
   version of the stub resolver will not need them anymore.  The
   public symbols for these functions remain in libresolv, and are not
   moved to libc, to avoid adding new symbol versions for legacy
   functions.  */
