Putting builtins in the std namespace

  I'm trying to digest your example.  Are you saying that you want:

    extern "C" {typedef unsigned int size_t ;}
    void *operator new (std::size_t) throw (std::bad_alloc);

to compile, with -fhonor-std, without any definition of `std::size_t'
in view?  There's an `#if 1' in your code that I don't understand.

I think I understand this variant:

  namespace _C_legacy {
    extern "C" {
      typedef unsigned int size_t;
    }
  } // namespace _C_legacy

  namespace std {
    using _C_legacy::size_t;
  } // namespace std

  void *operator new (std::size_t) throw (std::bad_alloc);

That, makes sense to me, and I'll try to get that working shortly.
