(defun which-func-identify-DEFUN ()
  (save-excursion
    (save-match-data
      (beginning-of-defun)
      (and (looking-at "DEFUN +(\"[^\"]+\",[ \n]+\\(F[^,]+\\),")
           (match-string-no-properties 1)))))

Likely the `save-match-data' is not required, but I tend to err on the
side of saving it on my code.

  (add-hook 'which-func-functions 'which-func-identify-DEFUN nil t)

on the required buffers (I set it through `c-mode-hook').
