Hi,

#include <stdio.h>

typedef int &r_type;
typedef const r_type cr_type;

template<class T>
struct A
{
  static const bool value = false;
};

template<>
struct A<int>
{
  static const bool value = true;
};

template<>
struct A<const int>
{
  static const bool value = true;
};

template<>
struct A<volatile int>
{
  static const bool value = true;
};

template<>
struct A<const volatile int>
{
  static const bool value = true;
};


int main()
{
  A<int> a1;
  printf("%d\n", a1.value);

  A<int &> a2;
  printf("%d\n", a2.value);

  A<const int &> a3;
  printf("%d\n", a3.value);

  A<volatile int &> a4;
  printf("%d\n", a4.value);

  A<const volatile int &> a5;
  printf("%d\n", a5.value);

  A<r_type> a6;
  printf("%d\n", a6.value);

  A<cr_type> a7;
  printf("%d\n", a7.value);

  return 0;
}

// output:
// 1
// 1
// 1
// 1
// 1
// 1
// 1


The instantiations with a reference type should use the primary class 
template and not one of the specializations.


bye, Christof
