No; but that doesn't mean much.

What about conflicting prototypes?  It is not a standardized function,
after all, as far as I know.

I'm not sure what a good policy on these kind of questions should be,
in general.  Either we assume the best, and fix things when people
complain.  Or we assume the worst, and risk overdoing things.  I tend
to prefer the former, because it tend to leave a trail of when and
what systems had some problem.  My impression is that currently gnulib
do a little bit of both at times.  Which may be perfectly fine too.
