+On platforms where @code{off_t} is a 32-bit type, @code{freopen} may not work
+correctly with files larger than 2 GB.  (Cf. @code{AC_SYS_LARGEFILE}.)

 On Windows platforms (excluding Cygwin), this function does usually not
 recognize the @file{/dev/null} filename.

+This function does not support a @code{NULL} file name argument on some

+OpenBSD 4.9, AIX 7.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 10, mingw, MSVC 9.

 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
+module freopen-safer can at least protect @code{stdin}, @code{stdout},
+and @code{stderr}.
