###  | # Boost.Regex ## regbase | ###

Use of the type `boost::regbase` is now deprecated, and the type does not form a part of the regular expression standardization proposal. This type still exists as a base class of `boost::basic_regex`, and you can still refer to `boost::regbase::constant_name` in your code, however for maximum portability to other std regex implementations you should instead use either:

    boost::regex_constants::constant_name

or

    boost::regex::constant_name

or

    boost::wregex::constant_name
