/* We use an UGLY hack to prevent gcc from finding us cheating.  The

   implementation of aio_error and aio_error64 are identical and so

   we want to avoid code duplication by using aliases.  But gcc sees

   the different parameter lists and prints a warning.  We define here

   a function so that aio_error64 has no prototype.  */
