为什么这不能编译?

#include "base.h"
#include <Poco/SharedPtr.h>
#include <Poco/AutoPtr.h>
#include <vector>
using Poco::SharedPtr;
using Poco::AutoPtr;

namespace kroll
{
    class Value;
    class KObject;
    class KMethod;
    class KList;
    class StaticBoundObject;
    class StaticBoundMethod;
    class StaticBoundList;
    class GlobalObject;
    class ScopeMethodDelegate;
    class Bytes;
    class VoidPtr;
    class ValueReleasePolicy;
    class Logger;
    class ArgList;
    template <class C>
    class KAutoPtr : public AutoPtr<C>
    {
    public:
        KAutoPtr() : AutoPtr()
        {}
        KAutoPtr(C* ptr) : AutoPtr(ptr)
        {}
        KAutoPtr(C* ptr, bool shared) : AutoPtr(ptr, shared)
        {}
        KAutoPtr(const AutoPtr& ptr) : AutoPtr(ptr)
        {}
        /*KAutoPtr& operator = (const AutoPtr& ptr)
        {
            return assign(ptr);
        }*/
#ifdef DEBUG
        //This is used in debug builds as a workaround to release all memory
        //before VS debugger incorrectly dumps it as memory leak.
        KObject* release()
        {
            KObject* t = _ptr;
            _ptr = 0;
            return t;
        }
#endif
    };

得到以下错误:

第66行是KAutoPtr(const AutoPtr&ptr): AutoPtr(ptr)

我使用命令行i686-apple-darwin10-gcc-4.2.1在MAC OS X 10.6.7机器上编译代码。
