hash_map<> and string...

[george at moberg dot com]

I'm using the last snapshot release w/gcc 2.95.2 on Linux and I want to
use hash_map<> with the string type as a key.  I end up having a header
that does this:

        /***************************************************************
         *
         *      Note:  This file used to contain a home-grown
associative
         *                 array class.  This was changed 3/8/2000 by
GTT to
         *                 use the Standard Library map<> class.  The
reason
         *                 it exists at all, is that hash_map<> doesn't
yet define
         *                 a hash function for the string class.
         *
         **************************************************************/

        #ifndef _ASSOC
        #define _ASSOC

        #include <hash_map>
        #include <string>

                //TODO:  Change to hash_map<string, T> and eliminate
this file.
        template <class T> class ASSOCIATION : public hash_map<string,
T>
        {
        public:
                ASSOCIATION() { };
                virtual ~ASSOCIATION() { };
        };

                //TODO:  Oops...linux doesn't define hash<string>...duh.
        __STL_TEMPLATE_NULL     struct hash<string>
        {
                size_t  operator()(const string& __s) const
		{
			return	__stl_hash_string(__s.c_str());
		}
        };

        #endif  // _ASSOC



Any plans to define hash<string> for the final release?  Anybody do this
already and it hasn't made it to a snapshot?
