[ros-users] Bond compile warnings on OSX Lion (XCode 4.3.2)

[Kevin Walchko]

Sorry … forgot to add. Changing it to:

// Internal use only
//struct BondSM
class BondSM
{
public:
  BondSM(bond::Bond *b_) : b(b_) {}
  void Connected();
  void SisterDied();
  void Death();
  void Heartbeat();
  void StartDying();

private:
  bond::Bond *b;
};

didn't seem to cause any issues … it compiled fine.
