I think that quite easy way to find such function is to use -Wall and -Werror options. Then, doing find . -exec grep -H -n 'func_name' {} \; on every error got during compilation will show all occurrences of function being called. Commenting the argument name or changing proto + def of function may be the longest task in this case.
