The unused attribute has existed since the 3.x days, I suggest enabling it with 4.x variants. Even if no warning is emitted, it doesn't hurt, and it will also take care of Clang for free.

I've found this to be a general problem which has a scope across many of our Boost libraries. Having the definition in boost/concept/detail/general.hpp is not sufficient. There are cases in Boost.Tuple, Boost.Bind and my Boost.Range library. I would love to be tackling and removing these annoying warnings, but I would like to avoid duplicating the unused attribute declaration. I am currently duplicating the attribute unused idiom in Boost.Range and attempting to ignore the noise from these warnings from other libraries.
I would be happy to be assigned this defect and sort this problem out if this helps.
