From: Samuel Thibault <samuel.thibault@ens-lyon.org>
-Subject: [PATCH] t/libpthread_sigs
+Subject: Enable global signal distribution in htl
-<patch description>
+* sysdeps/mach/hurd/htl/pt-sigstate-init.c (__pthread_sigstate_init):
+Call _hurd_sigstate_set_global_rcv().
+* sysdeps/mach/hurd/htl/pt-sigstate-destroy.c
+(__pthread_sigstate_destroy): Call _hurd_sigstate_delete().
+* sysdeps/mach/hurd/htl/pt-sigstate.c: Include <hurd/msg.h>
+(__pthread_sigstate): Use _hurd_sigstate_lock()/_hurd_sigstate_unlock()
+and _hurd_sigstate_pending(). Call __msg_sig_post() to wake up thread
+with pending signals.
+* sysdeps/mach/hurd/Makefile (LDLIBS-pthread.so): Add
+$(objdir)/hurd/libhurduser.so.
