10577,‘num_synchronizations’ declared in scope,M. Harper Langston <harperlangston@…>,Jeremiah Willcock,"In 1_54_0/boost/graph/distributed/detail/queue.ipp there is the following:

template<BOOST_DISTRIBUTED_QUEUE_PARMS>
bool
BOOST_DISTRIBUTED_QUEUE_TYPE::do_synchronize() const
{
#ifdef PBGL_ACCOUNTING
  ++num_synchronizations;
#endif

....

}

While editing a PBGL example to use Eager Dijkstra over Delta-Stepping, the following error was produced during compilation:

   ++num_synchronizations;

I couldn't locate num_synchronizations anywhere.  I could undefine PBGL_ACCOUNTING or just comment out the num_sync increment field.

I don't see this as having been fixed/removed in any other boost versions (checked 1_56_0).  Not a serious problem clearly unless accurate accounting is wanted.
