16stdout is created in 32-bit mode instead of 64-bit mode: Cygwin 1.5.x.
17One workaround is to use freopen(NULL, ``w'', stdout) on Cygwin 1.5.21
18or newer.  Another is to use the gnulib ftello module and do
19ftello(stdout).

21POSIX states that a setuid application can guarantee that fd 1 is
22open, but some systems guarantee this even for non-setuid programs.
23If an application is executed with fd 1 closed, use of @code{stdout}
24can affect an unrelated file that happened to be assigned to fd 1.
25The gnulib *-safer modules may be used to guarantee that fd 1 stays
26reserved for @code{stdout}.
