glibc/sysdeps/mach/hurd/sigstack.c
Roland McGrath 224a12bcb2 * sysdeps/mach/hurd/sigstack.c (sigstack): Remove `const' from
argument type, for 2000-02-22 change in signal/signal.h declaration.

	* sysdeps/generic/getdents64.c (__getdirentries64): Renamed
	to getdirentries64 (no __), since the Linux implementation
	has no __ name, and there is no declaration for the __ name.

	* sysdeps/mach/bits/libc-lock.h (__libc_cleanup_end): New macro.

	* sysdeps/mach/hurd/Makefile ($(common-objpfx)errnos.d): Tighten up
	sed regexp so as not to break directory names including /../ within.

	* sysdeps/unix/bsd/bits/waitflags.h: File removed.
	The sysdeps/generic file is right for BSD.  This file was in fact the
	Hurd file, but the only difference was the WNOREAP flag that was never
	actually implemented or used anywhere.
