is compatibility between boost and std. The filesystem_error exception will
return a boost ::system::error_code which is not compatible with
std::error_code as far as I can tell. Exception is not an option.

You could use LEAF to avoid having to translate between std::error_code and
boost::error_code in the first place. See
