explicit specialization; 'specialization' has already been defined

Duplicate explicit specializations are not allowed. For more information, see Explicit Specialization of Function Templates.

The following sample generates C2766:

// C2766.cpp
// compile with: /c
template<class T> 
struct A {};

struct A<int> {};

struct A<int> {};   // C2766
// try the following line instead
// struct A<char> {};
