--- Comment #6 from Paul Smith <psmith at gnu dot org> --- I'm happy to provide the source for DynamicBitSet (it's basically a union of a uint64_t and a boost::dynamic_bitset so that if you have <=64 bits you use the uint64_t and if you have >64 bits you use boost::dynamic_bitset). I have a hacked-up version of the original that removes all the unnecessary methods and also throws away some of the complexity for handling the small bitset leg of the union, which is not used in this example. Providing the Boost stuff is harder because, as I'm sure you're aware if you've used Boost, it's a LOT of headers and they all include others, etc. :). But I can try to get the necessary headers, or Boost can be downloaded separately.
