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