C++11 constructor inheritance and constructors with no parameters

In this piece of code, why is A's constructor with no parameters not inherited? Is there a special rule that prevents inheriting constructors with no parameters?

struct A {
    A(void *) {}
    A() {}
};

class B : public A {
public:
    using A::A;
    B(int x) {}
};

void f() {
    B b(1);
    B b2(nullptr);
    B b3; // error
}

clang++ -std=c++11 gives this error, and g++ -std=c++11 gives a substantially similar error message:

td.cpp:15:7: error: no matching constructor for initialization of 'B'
    B b3; // error
      ^
td.cpp:9:5: note: candidate constructor not viable: requires single argument 'x', but no arguments
      were provided
    B(int x) {}
    ^
td.cpp:8:14: note: candidate constructor (inherited) not viable: requires 1 argument, but 0 were
      provided
    using A::A;
             ^
td.cpp:2:5: note: inherited from here
    A(void *) {}
