[Boost-users] [shared_ptr] class ... has pointer data members but does not override ...

Hello,

a Boost newbie question:

Arch: PPC, OS: Mac OS X 10.4.10, Compiler: GCC 4.0.1

In a C++ dynamic library, I'm just developing, I have:
#include <boost/shared_ptr.hpp>
namespace MyNameSpace
{
     typedef boost::shared_ptr<std::string> StringPtr;
}

I get the following warning:
/usr/local/include/boost/shared_ptr.hpp: In instantiation of  
'boost::shared_ptr<std::string>':
/Volumes/blablabla/MyClass.cpp:81:   instantiated from here
/usr/local/include/boost/shared_ptr.hpp:131: warning: 'class  
boost::shared_ptr<std::string>' has pointer data members
/usr/local/include/boost/shared_ptr.hpp:131: warning:   but does not  
override 'boost::shared_ptr<std::string>(const  
boost::shared_ptr<std::string>&)'

The incriminated line in MyClass.cpp is the second line here:
__attribute__((visibility("default")))
MyNameSpace::StringPtr MyClass::myFunction() const
{
     /* .......... */
}

I have experienced the same with classes of my own instead of  
std::string, i.e. with
typedef boost::shared_ptr<MyOtherClass> MyOtherClassPtr;
etc.

May be it's just me, but the boost documentation and Google don't help.

Can I ignore the warnings or should I do something?

Thanks in advance
Klaus
