* 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.
