That is not necessarily true. These two defines have the following semantics:
1. If BOOST_NO_EXCEPTIONS is defined, libraries should not throw. One
option to implement that behavior is to pass exception objects (of the
usual documented library-defined types) to boost::throw_exception.
This imposes a requirement that the exception types must derive from
std::exception, but does NOT mean that they can't use the Boost
2. If BOOST_EXCEPTION_DISABLE is defined, then boost::throw_exception
does not inject the boost::exception class as a base. This prevents
boost/exception/exception.hpp from being included. However that header
does not include *any* headers, so the benefits in terms of
dependencies are mostly theoretical.
