This function cannot be easily and (more importantly) correctly ported
without cooperation from the libc stdio layer. We already document that
users should be prepared to have the function not available on some
platforms and that they should ideally switch their code to other
more portable and better interfaces.
Instead of making the build fail, and requiring porters to add
exceptions for something that most probably cannot be ported correctly
anyway, simply print a warning and let it build. This will not be a
regression because on those systems libbsd would have never been built
before.

While using fully uppercase man page titles has been the usual
convention for a very long time, it is rather ugly and something that
some other projects are switching away from.
groff(1) has changed the internal layout for the .Lb doc strings, but to
preserve backwards compatibility we cannot simply rename them, we need
to create new aliases so that these will work with old and new macros.

We have moved all man pages to section 3bsd, let's do the same for the
page title, and in all the references for uniformity and to avoid
confusions.

The funtools project ships a man page with the same, name. And although
it mith probably make more sense to rename the man page there, as BSD
systems will certainly not do so, this is the easiest and fastest way
to avoid a file conflict.
