Hmmm - my code looks like this:
throw some_error() <<
BOOST_ERROR_INFO <<
boost::error_info< tag_error_code >( boost::system::error_code( errno,
boost::system::errno_ec) );
I think there is no need for extra tags for error_code and
error_category. I suggest that both classes and your exception framework
should be in one boost library.
