The function was removed as part of the cleanup when I added support
for Ref_Type objects to the setkey function.  For example, it is now
possible to do

   private define foo ()
   {
      insert ("foo");
   }
   setkey (&foo, "^Cf");

As a work-around, you can use something like:

   static int is_key_bound (char *keyseq)
   {
      int type;

      if (1 != SLang_run_hooks ("get_key_binding", 1, keyseq))
        return 0;
      /* Two values are returned: type and func. */
      if ((-1 == SLdo_pop ())
          || (-1 == SLang_pop_int (&type)))
	return 0;
	
      return (type != -1);
    }
