Upgrading GTKD is definitely the best route. Most likely GTKD
will have done some changes since the last time you used it so
even if you upgrade GTKD you will still get errors but at least
GTKD will now correspond to the compiler version so your errors
will be fixable on your projects side and you wont have to fix
anything on the library's side.
