get_current_file_name missing during compilation

[aaronovz1]

I am testing upgrading from boost 1.64 to 1.67 and I am getting a compilation error under GCC 5.4:

error: 'boost::log::v2s_mt_posix::aux::locking_ptr<boost::log::v2s_mt_posix::sinks::text_file_backend, boost::recursive_mutex>::element_type {aka class boost::log::v2s_mt_posix::sinks::text_file_backend}' has no member named 'get_current_file_name'

It doesn't really make sense to me because using the rotate_file() function and some others works fine, and they are defined in the same class. I thought it was a precompile/obj issue so I cleaned out the entire project and recompiled but that did not fix it.
