You're technically correct but this dependence is very lightweight: a
single file (boost/exception/exception.hpp) designed specifically for
that purpose. It's about 200 lines of self-contained code which
doesn't include anything. This code is needed to enable the use of the
rest of Boost Exception, which can not work without it.

That said, the user can specify BOOST_EXCEPTION_DISABLE to disable the
integration of Boost Exception into boost::throw_exception. See
www.boost.org/doc/libs/release/libs/exception/doc/configuration_macros.html.
