The patch makes changes which will break modes in emacs 25, so I'm
interested in knowing how to adapt, in particular, so my mode (and
others) can be backward compatible.
I think I have figured out how to accomodate this change: just checking
for c-make-inherited-keymap and c-derivative-mode, so I am happy.

Nope, for some reason, doing (c-make-inherited-keymap) in the map
definition in 24, I end up only with a Foo++ menu. Simply using
(make-keymap), I'd end with with both Foo++ and C++ menus.

Oh, it was broken because I was using (make-syntax-table) instead of
(funcall (c-lang-const c-make-mode-syntax-table c)). It looks like
c-derivative-mode comes with no syntax table, which is alright.
