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.

+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
