   * For providing a substitute for a function that is missing on some
     platforms, but is declared and works fine on the platforms on which
     it exists:

       #if @GNULIB_FOO@
       # if !@HAVE_FOO@

   * For providing a replacement for a function that exists on all platforms,
     but is broken/insufficient and needs to be replaced on some platforms:

       #if @GNULIB_FOO@
       # if @REPLACE_FOO@
