In terms of what headers are included by boost/throw_exception.hpp,
the only difference BOOST_EXCEPTION_DISABLE makes is that it prevents
boost/exception/exception.hpp and boost/current_function.hpp from
being included, however these headers don't include anything and are
*very* lightweight.

With or without BOOST_EXCEPTION_DISABLE boost/throw_exception.hpp includes:

#include <boost/exception/detail/attribute_noreturn.hpp>
#include <boost/detail/workaround.hpp>
#include <boost/config.hpp>
#include <exception>
