FSFmacs-20.2's font-lock has `c-font-lock-extra-types' (same for C++). Use the corresponding entries with the form (eval . FORM), see `font-lock-keywords'.

If there is such a variable, it should be a 'risky-local-variable since you can include any code.

The concept of `font-lock-fontify-region-function' in FSFmacs-20.2 is more general.
