[BZ #2978]
2006-08-03 Ulrich Drepper <drepper@redhat.com>
* rt/Makefile (tests): Add tst-clock2.
* rt/tst-clock2.c: New file.
[BZ #2978]
* resolv/gai_notify.c (__gai_notify_only): Copy memory for thread
function and its parameters and pass it to new thread.
(__gai_notify): Add support for alternative waiting for completion.
* resolv/gai_suspend.c (gai_suspend): Add support for alternative
waiting for completion.
* resolv/getaddrinfo_a.c: Likewise.
* resolv/gai_misc.h (struct waitlist): Don't add cond if alternative
waiting for completion is used.
* resolv/gai_misc.c: Allow overwriting code to start helper thread.
* resolv/gai_cancel.c: Include <gai_misc.h> not "gai_misc.h".
* resolv/gai_error.c: Likewise.
* resolv/gai_sigqueue.c: Likewise.
* hurd/getdport.c (__detdport): Don't return EBADF; instead set
errno to EBADF and return MACH_PORT_NULL.
* posix/Makefile (CFLAGS-waitid.c): Add -fasynchronous-unwind-tables.
