ambiguous call to overloaded template function

[Ruki]

I want to overload function to swap two others types, for example,
type<T>, T* and so on,
but I can't compile the following code at VC 6.0.

The compiler says :
error C2667: 'swap' : none of 2 overload have a best conversion
error C2668: 'swap' : ambiguous call to overloaded function
-------------------------------------------------------------------------------------------------------------
template < typename T >
void swap(T &lhs, T &rhs)
{
// do some thing
}

template < typename T >
void swap(T *lhs, T *rhs)
{
// do some thing
}

template < typename T >
struct type{};

template < typename T >
void swap(type<T&lhs , type<T&rhs)
{
// do some thing
}
int main()
{
int *p1,*p2;
type<intt1, t2;
swap(t1, t2);
swap(p1, p2);

I need compiler compatibility

I also need use std::swap specialization for my own types even if i
use std::swap
