SparseBitVector compile warning

The warning is:

The problem is in the SpareBitVector.h file, line 58:
  friend class ilist_sentinel_traits<SparseBitVectorElement>;
It should be struct, not class, as ilist_sentinel_traits is a struct,
not a class:
  friend struct ilist_sentinel_traits<SparseBitVectorElement>;

Done. Thanks!
