Comment (by barendgehrels):

 Yes, disabling might be an option. However, we get the chance then that
 gcc or clang still complain (did not check).

 Another option is adding boost::ignore_unused_variable_warning(n); that is
 quite easy to do ;-) This is valid for all compilers, and is not taking
 runtime. I did that earlier for some strategies, so it can also be done
 for fp_strategy.

 This might be done for most (but probably not all) your reported warning
 problems.
