Death to macros! No more macros!

How about defining those templates instead? They're all pretty simple,
e.g.:

    template<typename T>
    T bit_and<T>(T a, T b)
    {
      return a & b;
    }

This isn't exactly the same as std::bit_and, but I think it should
work for this case.

What's the earliest gcc version we're targetting? Is it still 4.1 or
thereabouts? I can't wait to use C++11 features. I'm hoping next year
we can start doing that.
