  New module 'fstatat', split off from module 'openat'.
  
  * lib/openat.h (statat, lstatat): Enable only if GNULIB_FSTATAT is
  defined.
  * m4/fstatat.m4: New file. extracted from m4/openat.m4.
  * m4/openat.m4 (gl_FUNC_OPENAT): Don't set GNULIB_FSTATAT. Don't invoke
  gl_FUNC_FSTATAT.
  (gl_FUNC_FSTATAT): Moved to m4/fstatat.m4.
  * modules/fstatat: New file, extracted from modules/openat.
  * modules/openat (Files): Remove lib/fstatat.c.
  (Depends-on): Remove lstat.
  (configure.ac): Remove AC_LIBOBJ of fstatat.
  * modules/fstatat-tests: New file, extracted from modules/openat-tests.
  * modules/openat-tests (Files): Remove tests/test-fstatat.c,
  tests/test-lstat.h, tests/test-stat.h.
  (Depends-on): Remove getcwd-lgpl.
  (Makefile.am): Remove rules for test-fstatat.
  * doc/posix-functions/fstatat.texi: Mention module 'fstatat' instead
  of module 'openat'.
  * NEWS: Mention the change.
  * modules/getcwd (Depends-on): Add fstatat.
  * modules/linkat (Depends-on): Likewise.

  Gnulib module: fstatat
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  glibc 2.3.6, MacOS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8,
  AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Cygwin 1.5.x, mingw, MSVC 9, Interix 3.5, BeOS.
  But the replacement function is not safe to be used in libraries and is not multithread-safe.
  @item
  On platforms where @code{off_t} is a 32-bit type, @code{fstatat} may
  not correctly report the size of files or block devices larger than 2
  GB.  (Cf. @code{AC_SYS_LARGEFILE}.)
  @item
  On some platforms, @code{fstatat(fd,"file/",buf,flag)} succeeds instead of
  failing with @code{ENOTDIR}.
  Solaris 9.
  @item
  For symlinks, when the argument ends in a slash, some platforms don't
  dereference the argument:
  Solaris 9.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  On Windows platforms (excluding Cygwin), @code{st_ino} is always 0.
  @item
  On some file systems, @code{st_size} contains bogus information for
  symlinks; use the gnulib module areadlink-with-size for a better way
  to get symlink contents.
  @end itemize
