Are you using the version of xpressive in 1.34, or in the latest .zip archive from the Boost file vault? In the latest code, I have tried to stifle these warnings by adding the following to regex_primitives.hpp: namespace detail { inline void ignore_unused_regex_primitives() { ignore_unused(repeat_max); ignore_unused(inf); ignore_unused(epsilon); ... ignore_unused(keep); } } where ignore_unused() is merely: template<typename T> void ignore_unused(T const &) { } That seems to work for me. You might try something similar. -- Eric Niebler Boost Consulting www.boost-consulting.com
