This is a possible fix (subject to typos) :

template <typename T>
struct greedy_implicit_value : public po::typed_value<T>
{
  using base = po::typed_value<T>;

  greedy_implicit_value(const T& value) : base(nullptr)
  {
    base::implicit_value(value);
  }

  bool adjacent_tokens_only() const override { return false; }
unsigned max_tokens() const override { return 1; }
};

template <typename T>
po::typed_value* implicit_value(const T& value)
{
  return new greedy_implicit_value<T>(value);
}
