/* We use an UGLY hack to prevent gcc from finding us cheating. The
implementation of aio_fsync and aio_fsync64 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_fsync64 has no prototype. */
