  Sync from coreutils.
  * lib/.cppi-disable: Add getaddrinfo.h, getdelim.h, getline.h, getpass.c
  mbchar.h, mbuiter.h, strcase.h, strnlen.h, strnlen1.h.
  * lib/.cvsignore: Add fts.h, search.h, t-fpending.
  * lib/settime.c (settime): Fix { typo in previous patch.  Also, don't
  bother returning ENOSYS if settimeofday or stime fails; just let
  them return whatever errno they want to return.
  * lib/utimens.c: Include unistd.h, for dup2.
  (futimens): Fix typo: HAVE_FUTIMESAT was misspelled in an #if.
  (futimens) [! HAVE_FUTIMESAT]: If !file, set errno before returning -1.
  * lib/fts-cycle.c [HAVE_CONFIG_H]: Include <config.h>.
  * lib/openat-die.c: Use `#ifdef HAVE_CONFIG_H', not `#if HAVE_CONFIG_H'.
  * lib/openat.c (fdopendir): Do not define if HAVE_FDOPENDIR.
  Remove AT_FDCWD test.
  Do not consume the fd unless successful.
  * lib/openat.h (fdopendir): Do not define if HAVE_FDOPENDIR.
  * lib/settime.c (settime): Move the HAVE_STIME block `up' into an #elif
  block, so that we don't even try to compile it if settimeofday is
  available.  This works around a compilation failure on OSF1 V5.1,
  due to stime requiring a `long int*' while tv_sec is `int'.
  * m4/openat.m4 (gl_FUNC_OPENAT): Check for fdopendir.
  * m4/ullong_max.m4 (gl_ULLONG_MAX): Simplify so that it merely
  defines ULONG_MAX_LT_ULLONG_MAX.  Thomas M.Ott reports that
  ULLONG_MAX doesn't work with 2.7.2.1.
  * m4/utimes.m4 (gl_FUNC_UTIMES): Detect the version of utimes
  from glibc-2.2.5 that fails for read-only files.
  * m4/chdir-long.m4 (gl_FUNC_CHDIR_LONG): Compare $gl_have_path...
  against `yes', rather than just testing for nonempty.
