Subject: * sysdeps/mach/hurd/sigwait.c (__sigwait): Use __sigandset,
X-Git-Tag: upstream/2.30~22207
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=05dea6d10c72d7604d289eca4d39dadeda7e88ac;p=external%2Fglibc.git

* sysdeps/mach/hurd/sigwait.c (__sigwait): Use __sigandset,

	__sigisemptyset.  Don't use MASK uninitialized.

	* sysdeps/mach/hurd/sigprocmask.c (__sigprocmask): Use __sigorset.
	* hurd/hurdinit.c (_hurd_new_proc_init): Use __sigisemptyset.
	* hurd/hurdsig.c (_hurd_internal_post_signal): Use __sigismember,
	__sigdelset, __sigaddset, __sigorset.
