Well, we really don't use libncurses here.  libtinfow might indeed
come from there, but it is not it, so I personally don't think there
is a problem.

That being said, bison was probably not linked against it directly.
Grep did not find occurrences of tinfow in Bison's tarball.
It was most probably inherited from libtextstyle.so.0, so that's
where you should look for such a feature.
