示例1: T
namespace InhCtor {
struct A {
A(int);
protected:
int T();
};
typedef A T;
struct B : A {
// This is a using-declaration for 'int A::T()' in C++98, but is an
// inheriting constructor declaration in C++11.
using InhCtor::T::T;
};
#if __cplusplus < 201103L
B b(123); // expected-error {{no matching constructor}}
// [email protected] 2{{candidate constructor}}
int n = b.T(); // ok, accessible
#else
B b(123); // ok, inheriting constructor
int n = b.T(); // expected-error {{'T' is a protected member of 'InhCtor::A'}}
// [email protected] {{declared protected here}}
// FIXME: EDG and GCC reject this too, but it's not clear why it would be
// ill-formed.

struct U : S { // expected-note 6{{candidate}}
