  Gnulib module: openat
  
  Portability problems fixed by Gnulib:

  This function is missing on some platforms:
  glibc 2.3.6, MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0, OpenBSD 3.8, AIX
  5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 1.5.x, mingw, Interix 3.5, BeOS.
  But the replacement function is not safe to be used in libraries and is not multithread-safe.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  Some platforms do not allow changing the access bits on symbolic
  links.  POSIX states that @code{fchmodat(@dots{},AT_SYMLINK_NOFOLLOW)}
  may fail with @code{EOPNOTSUPP} when called on a symlink, but some
  platforms, as well as the gnulib replacement, fail for any use of
  AT_SYMLINK_NOFOLLOW even if the target was not a symlink:
  glibc, Cygwin.
