> This seems like a different in impl. of std::map in vc7 for an 
> example following fragment produces the same error
> #include <map>
> int main()
> {
> 	std::map<const int, int> test;
> 	return 0;
> }
> if you remove "const" qualifier from the key this goes away.
> Why? it looks likes making the key const removes the difference between 
> a pair<key, value> and a const version of the same.
> vc7 std::map impl. is
> template<class _Kty,
> 	class _Ty,
> 	class _Pr = less<_Kty>,
> 	class _Alloc = allocator<pair<const _Kty, _Ty> > >
> 	class map{...}
> but in vc6 std::map impl. is
> template<class _K, class _Ty, class _Pr = less<_K>,
> 	class _A = allocator<_Ty> >
> 	class map {...}
> Elements-key of a map has been changed so that they are immutable and a
> const qualifier is no longer required.
