template specialization

Hi Everyone,

 I have the following code,


template<typename T>
void funn(T a)
{
 printf("function invoked...\n");
}

template<>
void funn<int>(int aa)
{
 printf("second function is invoked...\n");
}

void funn(int a)
{
 printf("third function is invoked...\n");
}


int main()
{
 funn(2);
}


 And i get the following output,

 third function is invoked...

But i expected a compilation error "funn(int) redefined", does the
standard say anything about this?

Thanks in advance ! ! !
