So you would contend that

  int x;
  #pragma omp threadprivate(x)

  void broadcast()
  {
  #pragma omp parallel copyin(x)
    ;
  }

Must instead be written

  void broadcast()
  {
  #pragma omp parallel
  #pragma omp single copyprivate(x)
    ;
  }

Or does your contention apply to *all* omp directives, and thus the
only way to correctly write this function is to somehow write a body
that the compiler can't optimize away.
