/* We use an UGLY hack to prevent gcc from finding us cheating.  The
   implementation of aio_return and aio_return64 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_return64 has no prototype.  */
