	* version.c (banner): New static const variable, complete version
	banner text.
	(__libc_print_version): Use it, and use __write instead of printf.

	* configure.in (sysnames): Don't cache the value, because it
 	depends only on libc sources.  Merge uniquifying third pass into
	Implies/parent expansion second pass.  Report each unique name as
	it is added in partial report string, terminated when finished.

	* Makeconfig (sysdep_dir): Move defn before config.status rule that
	expands it.
	(sysdep-configures): Variable removed.
	(config.status): Use its contents directly, tighten up a bit, and
	include Implies files.

	* elf/dl-open.c (_dl_open) [PIC]: Set PARENT to _dl_loaded if null.

	* elf/Makefile ($(objpfx)$(rtld-installed-name)): Make a symlink.

	* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_open_zero_fill):
	Add comment.

	* elf/rtld.c (dl_main): Close _dl_zerofd after mapping deps.

	* sysdeps/generic/machine-gmon.h [NO_UNDERSCORES]: Define mcount as
	weak alias for _mcount.
	* sysdeps/alpha/_mcount.S (mcount): Define as weak alias.
