No, there is nothing like this in C++. The C library is part of C++ by
explicit inclusion, not by compatibility.
Consider, for example, general purpose functions, like rand() (this one
declared in <cstdlib>). It does not make any sense to say that such
functions are C-compatibility stuff only, because that would imply that
it's not possible to do even such basic things in "pure" C++.
C++ *contains* the C library. It uses different header names (for
example, cstdlib instead of stdlib.h) and namespace std (so that you
have std::rand, std::printf, etc.), but everything is there and
everything is part of C++. Including NULL.
