typedef name as identifier of constructor/destructor

Description: As per the C++98 a constructor declarator can be a typedef name if the declaration is inside class member specification. It must not be allowed if the declaration is done outside the class member specification.

But the both GCC and VC++ differs in the behaviour. VC++ have correct implementation compared to gcc 3.4.2. Consider the following example,

Example:

class Alpha;
typedef Alpha Constructor;

class Alpha
{
public:
Constructor::Constructor(){}
};

int main()
{
Alpha obj;
}
Explanation:

If you compile the above program using VC++ it will be getting compiled. But if you use the gcc 3.4.2 it will not compile.

I think it is a mistake with GCC because they did not take care of this point in the ISOC++98 standard. And it may be an implementation artifact of Visual C++ that gets this code compiled.
