	* sysdeps/pthread/aio_misc.h (struct waitlist): Add result member.
	* sysdeps/pthread/aio_notify.c (__aio_notify): For synchronous waiters,
	failed I/O, and a result pointer, set value to -1.
	* sysdeps/pthread/aio_suspend.c: Initialize result pointer to NULL.
	* sysdeps/pthread/lio_listio.c: For LIO_WAIT, point result pointer in
	wait list to local variable result.  If nonzero afterwards, set errno

/* The socket-oriented system calls are handled unusally in Linux.
They are all gated through the single `socketcall' system call number.
`socketcall' takes two arguments: the first is the subcode, specifying
which socket function is being called; and the second is a pointer to
the arguments to the specific function.
The .S files for the other calls just #define socket and #include this.
They also #define a 'number-of-arguments' word in NARGS, which
defaults to 3. */
