A header to use the hash_map<Key,Type> (same member functions/objects as a std::map<Key,Type>) which is not in the stl library:

#ifdef __GNUC__
        #if __GNUC__ < 3
                #include <hash_map>
        #else
                #include <ext/hash_map>
                #if __GNUC_MINOR__ == 0
                        using namespace std;       // GCC 3.0                                                                                          
                #else
                        using namespace __gnu_cxx; // GCC >= 3.1                                                                                  
                #endif
        #endif
#endif
