As far as I can tell, this _is_ used.
boost/graph/graph_concepts.hpp contains the following:
#if !defined(BOOST_NO_ARGUMENT_DEPENDENT_LOOKUP) \
&& !BOOST_WORKAROUND(__GNUC__, <= 2) \
&& !BOOST_WORKAROUND(__BORLANDC__, BOOST_TESTED_AT(0x564))
# define BOOST_VECTOR_AS_GRAPH_GRAPH_ADL_HACK
template <class T>
typename T::ThereReallyIsNoMemberByThisNameInT vertices(T const&);
This line is mentioned in the error message, so
BOOST_VECTOR_AS_GRAPH_GRAPH_ADL_HACK _is_ indeed defined.
