[Boost-users] Tuple.hpp: initialization data in header

My compiler is complaining that tuple_basic.hpp has data initialization in header, at this line: detail::swallow_assign const ignore = detail::swallow_assign(); Because of this, it can't cache the headers, and compilation times goes turtle speed. Is there a simple way to overcome this, without the need to create a .cpp and linking it or without using macros?? Thanks :)
