[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.
