unless you have some other special plan, I would suggest defining the
std::__nullptr_t typedef in c++config (of course conditional to
__GXX_EXPERIMENTAL_CXX0X__), then cstddef, functional, shared_ptr,
unique_ptr, whatever else, can automatically use it as an implementation
detail. That would be consistent with the way I'm going to avoid
including <cstddef> as an implementation detail in the headers: I mean
to add typedefs of the form:

namespace std
{
    typedef __SIZE_TYPE__ size_t;
    typedef __PTRDIFF_TYPE__ ptrdiff_t;
  ...
}

to c++config.
