It is telling you that it has not yet seen a defintion or a
declaration of anything named '__gnu_cxx::hash_set'.

I can't reproduce this warning on Linux with g++ 3.1, 3.2, 3.3,
3.4.3 or 4.0. 

Perhaps it would help to know the output from your 'g++ --version'.
Also, a minimal test case might help. Here is what I compiled cleanly:

  $ cat junk.cc
  #include <ext/hash_set>
  using __gnu_cxx::hash_set;
  int main() { return 0; }

Cheers,
