    On the other hand when __cplusplus is defined they define it to the
    "__null" builtin, which GCC uses to give type conversion errors for
    "int foo = NULL" but not "char *foo = NULL". A "((void *)0)"
    definition gives C++ type errors for both due to the broken C++ void
    pointer conversion problems.
