/* We use an UGLY hack to prevent gcc from finding us cheating.  The
Packit 6c4009
   implementation of aio_cancel and aio_cancel64 are identical and so
Packit 6c4009
   we want to avoid code duplication by using aliases.  But gcc sees
Packit 6c4009
   the different parameter lists and prints a warning.  We define here
Packit 6c4009
