The hashing-related functions are in a different namespace in
recent versions of libstdc++.  The code needs to 
   #include <ext/hash_map>
and perhaps something like this:
   using namespace __gnu_cxx;

Though I recall once just giving up on hash tables altogether
because it was too painful to get autoconf to find the right
set of headers and namespaces.
