The cast isn't nice though. Either change the signature of
is_same_parameter() to match walk_parameter_dep_func or, if that
really isn't an option, add a wrapper function with the correct
signature and use that here instead. Even if you prefer the latter,
it's probably better to do that only when you need it, in a later
patch.
