  Gnulib module: open, fchdir
  
  Portability problems fixed by the Gnulib module open:
  @itemize
  @item
  This function does not fail when the file name argument ends in a slash
  and (without the slash) names a nonexistent file or a file that is not a
  directory, on some platforms:
  FreeBSD 7.2, AIX 7.1, HP-UX 11.00, Solaris 9, Irix 5.3.
  @item
  This function does not support the @code{O_NONBLOCK} flag when it is defined
  by the gnulib module @code{nonblocking} on some platforms:
  mingw.
  @item
  On Windows platforms (excluding Cygwin), this function does usually not
  recognize the @file{/dev/null} filename.

  Portability problems fixed by the Gnulib module fchdir:
  @itemize
  @item
  On Windows platforms (excluding Cygwin), this function fails to open a
  read-only descriptor for directories.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  On Windows, this function returns a file handle in @code{O_TEXT} mode by
  default; this means that it translates '\n' to CR/LF by default.  Use the
  @code{O_BINARY} flag if you need reliable binary I/O.
  @item
  On platforms where @code{off_t} is a 32-bit type, @code{open} may not work
  correctly with files larger than 2 GB.  The fix is to use the
  @code{AC_SYS_LARGEFILE} macro.
  @end itemize
