Since we are not going to do anything with them, they are not even going to 
be dereferenced, they will just get tossed out.  What scenario do you have 
in mind?

class A
{
  int x, y;

public:
  A() { x = 0; y = 0; }
  ~A() { }
};

main()
{
  class A x;
#pragma omp parallel private (x)
    {
    }
}

Why would it be unsafe to replace that empty directive with (void)0?
