Sorry, bad wording. What I'm trying to say is that if you remove a
function check just because it is not used by the codebase today maybe
some programmer will need that function tomorrow. And adding an autoconf
check is far from trivial, at least for those not familiarized with the
autotools.

IMHO removing configure checks because they are not used by the codebase
right now is not an improvement similar to removing dead code from the
C++ sources.
