That was the reply on the original patch, so I thought that I can omit 
the description, sorry.

That patch makes "set print object" option affect MI interface. Here is 
an example:

struct Base {
    Base() : a(1) {}
    virtual ~Base() {}  // Enforce type to have RTTI
    int a;
};

struct Derived : public Base {
    Derived() : b(2) {}
    int b;
};

int main() {
    Derived b;
    Base* aPtr = &b;
    return 0;                  // [1]
}


Start gdb in MI mode and run to line [1]. Make -var-create for aPtr. If 
"set print object" is "on" you will see the type Derived* for the 
created varobj.
