[Boost-users] [Exceptions] Boost exception relationship with std exception & streams

I'm about to use boost.exception in a library which may require to be built in environnement where using std is eitehr impossible or has huge penalty one may want to avoid. My main idea was to use the BOOST_THROW_EXCEPTION and the error_info to build the diagnostic infos into exception class then: - if BOOST_NO_EXCEPTIONS is not set, process normally - if BOOST_NO_EXCEPTIONS is set, then jump into a throw_exception function that just stream diagnsotic_info to cerr or some such - if BOOST_NO_EXCEPTIONS and NT2_NO_STREAM is set, jump to a throw_exception that fprintf the diagnostic_info to stderr My question is: how deeply std elements ar eintegrated in boost::exception and is this kind of scheme workable with current version ?
