  fdopendir: detect FreeBSD bug
  
  FreeBSD fdopendir(fd) always consumes fd, even if it fails with
  ENOTDIR.  The code that works around the GNU Hurd bug also fixes this;
  we just need to detect it.
  
  * m4/fdopendir.m4 (gl_FUNC_FDOPENDIR): Detect bug.
  * doc/posix-functions/fdopendir.texi (fdopendir): Document it.

  Gnulib module: fdopendir
  
  Portability problems fixed by Gnulib:

  This function is missing on some platforms:
  glibc 2.3.6, MacOS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, AIX
  5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, 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.  Also, the replacement does not guarantee
  that @samp{dirfd(fdopendir(n))==n} (dirfd might fail, or return a
  different file descriptor than n).
  @item
  This function exists but is not declared on some platforms:
  FreeBSD 7.3.
  @item
  This function does not reject non-directory file descriptors on some
  platforms:
  GNU/Hurd.
  @item
  This function mistakenly closes non-directory file descriptors on some
  platforms:
  FreeBSD 8.1.
