  symlinkat: port to AIX 7.1
  
  * doc/posix-functions/symlinkat.texi (symlinkat):
  Mention AIX porting problem.
  * lib/symlinkat.c: Always include errno.h.
  (rpl_symlinkat) [HAVE_SYMLINKAT]: New function.
  * lib/unistd.in.h (symlinkat): Add replacement machinery.
  * m4/symlinkat.m4 (gl_FUNC_SYMLINKAT): Check symlinkat behavior.
  * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Add REPLACE_SYMLINKAT.
  * modules/symlinkat (Depends-on): Add fstatat if REPLACE_SYMLINKAT.
  (configure.ac): Also compile replacement if REPLACE_SYMLINKAT.
  * modules/unistd (unistd.h): Substitute REPLACE_SYMLINKAT.

  Gnulib module: symlinkat
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  On some systems, @code{symlinkat(value, fd, "name/")} mistakenly creates a
  symlink:
  AIX 7.1.
  @item
  This function is missing on some platforms:
  glibc 2.3.6, Mac OS 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, Solaris 10, 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
  Some platforms declare this function in @code{stdio.h} instead of
  @code{unistd.h}:
  Cygwin 1.7.1.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function always fails with @samp{ENOSYS} on platforms that don't
  support symlinks:
  mingw, MSVC 9.
  @end itemize
