Summary: g++ doesn't use default constructor properly

Initial Comment:
hii , 

#include<iostream>
using namespace std;
class rational{
        int a;
public:
        rational(int a=1):a(a){}
        ~rational(){}
        friend bool operator ==(const rational&,const rational&);
};
 
bool operator==(const rational& a,const rational& b){
        return  (a.a==b.a) ;
}
int main(){

        rational c,d;
        bool x = c==d;
        bool y = 1==c;
        cout << x << y <<endl;
        return 0;
}

i tried to compile this code on g++ without any other flag , but gave me :
couldn't find operator== for (1==c) or something like that . 
but this code should work properly , i have a default constructor .
so when callinng (1==c) 1 should be casted as a rational and compared .
i tried this in linux terminal and it worked fine .
