  Gnulib module: freopen
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  On Windows platforms (excluding Cygwin), this function does usually not
  recognize the @file{/dev/null} filename.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  On Windows platforms (excluding Cygwin), this function does not set @code{errno}
  upon failure.
  @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:
  HP-UX 11.00, Solaris 9, Irix 5.3.
  @item
  Applications should not assume that @code{fileno(f)} will be the same
  before and after a call to @code{freopen(name,mode,f)}.  However, the
  module freopen-safer can at least protect @code{stdin}, @code{stdout},
  and @code{stderr}.
  @end itemize
