Emacs C++ Mode: Highlighting Casts and Sizeof

Question

I am using the standard (shipped) Emacs C++ mode but I have a slight itch that I am looking to get scratched. How would I go about properly highlighting the types inside of a sizeof and the casts in C++?

For example:

1. A Cast

   Type * pointer = reinterpret_cast <Type *> (original);

2. Sizeof

   std::cout << sizeof (Type) << "\n";
