I don't think it does.
- First, make stderr always unbuffered. That's what you get on
most platforms anyway.
- Then, somewhere along fputs_unfiltered or some central output routine,
keep track of which was the last to be used between stdout and stderr.
If outputting to stderr, flush stdout first. Don't need to do the
opposite, since stderr will always be unbuffered.
