The code:

struct X {
    explicit X(int n) : value(n) {}

    // error C2664: 'X::X(const X &)' : cannot convert parameter 2 from 'int' to 'const X &'
    // works without the explicit keyword in X(int) constructor
    X() : X(0) {}

    int value;

int main()
    X x;

This is not correct. It should compile fine and compiles in gcc-4.5.1 and other compilers supporting C++11.
