VC2013が無名構造体のメンバに初期値を記述しても初期化してくれない

VisualStudio2013のC++11実装が甘い。

// hoge.cpp
#include <stdio.h>

struct Hoge {
    int one = 11;
    int two = 12;
    int sun = 13;

    struct named_t {
        int one = 21;
        int two = 22;
        int sun = 23;
    } named;

    struct {
        int one = 31;
        int two = 32;
        int sun = 33;
    } noname;
};

int
main(int, const char**) {
    Hoge hoge;
    printf("hoge.one = %d\n", hoge.one);
    printf("hoge.two = %d\n", hoge.two);
    printf("hoge.sun = %d\n", hoge.sun);
    printf("hoge.named.one = %d\n", hoge.named.one);
    printf("hoge.named.two = %d\n", hoge.named.two);
    printf("hoge.named.sun = %d\n", hoge.named.sun);
    printf("hoge.noname.one = %d\n", hoge.noname.one);
    printf("hoge.noname.two = %d\n", hoge.noname.two);
    printf("hoge.noname.sun = %d\n", hoge.noname.sun);
    printf("ok.\n");
    return 0;
}

# SConstruct

警告も出さないとかマジかVC…。初期値記述するときは無名構造体を使うのはやめよう。
