 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’ was not declared in this scope
    ++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.
