Partially revert commit
536d47bd9d5fce8d91929bee3128fa1d08dbcc57.
Per buildfarm, the "#ifdef F_SETFD" removed in that commit actually
is needed on Windows, because fcntl() isn't available at all on that
platform, unless using Cygwin. We could perhaps spell it more like
"#ifdef HAVE_FCNTL", or "#ifndef WIN32", but it's not clear that
those choices are better.
It does seem that we don't need the bogus manual definition of
FD_CLOEXEC, though, so keep that change.
