Luca Bacci 8264b13737 tests/cxx: Do not assume that NULL is a pointer type starting with C++11
Many toolchain did not change the definition of NULL to avoid introducing
breaking changes in existing codebases. For example, on Windows NULL is
0 (int) regardless of the C++ standard in use.

Fixes the following warnings on CLang when compiling for Windows:
