+ * sysdeps/unix/sysv/linux/i386/syscalls.list: Add time syscall.
+
+ * elf/Makefile: Use LC_ALL=C in a few cases where we call external
+ text processing tools.
+
+ * sysdeps/pthread/aio_misc.h (struct waitlist): Don't add caller_pid
+ element unless BROKEN_THREAD_SIGNALS is defined.
+ (struct requestlist): Likewise.
+ * sysdeps/pthread/aio_misc.c (__aio_enqueue_request): Don't fill in
+ caller_pid of new request unless BROKEN_THREAD_SIGNALS is defined.
+ * sysdeps/pthread/aio_suspend.c (aio_suspend): Likewise.
+ * sysdeps/pthread/aio_notify.c (__aio_notify_only): Remove caller_pid
+ parameter unless BROKEN_THREAD_SIGNALS is defined. Adjust callers.
+ Pass current PID to __aio_sigqueue.
+ * sysdeps/pthread/lio_listio.c (lio_listio): Adjust __aio_notify_only
+ call. Don't initialize caller_pid field of waitlist element.
