13 Portability problems not fixed by Gnulib:
16 stderr is created in 32-bit mode instead of 64-bit mode: Cygwin 1.5.x.
17 One workaround is to use freopen(NULL, ``r+'', stderr) on Cygwin 1.5.21
18 or newer. Another is to use the gnulib ftello module and do
21 POSIX states that a setuid application can guarantee that fd 2 is
22 open, but some systems guarantee this even for non-setuid programs.
23 If an application is executed with fd 2 closed, use of @code{stderr}
24 can affect an unrelated file that happened to be assigned to fd 2.
25 The gnulib *-safer modules may be used to guarantee that fd 2 stays
26 reserved for @code{stderr}.
