When I want to use exceptions and also Boost.Exception, I have my_app
-> exception in addition to my_app -> your_library -> utility ->
exception. The dependency to exception does not bother me. I have that
anyway.

When I don't want to use Boost.Exception (BOOST_EXCEPTION_DISABLE), or
don't want to use exceptions at all (BOOST_NO_EXCEPTIONS), I have
my_app -> your_library -> utility. It should stop there.

I was referring to <boost/exception/exception.hpp>. This should not be
needed when BOOST_NO_EXCEPTIONS is defined, as throw_exception takes
std::exception, not boost::exception.
