Доброго времени суток. :)

Возможно Вам покажется, что я - один из суперменов или идиотов, но всё же хочется задать такой вопрос:

Почему в GCC может не компилироваться сей код?

#include <vector>
#include <algorithm>

using namespace std;

typedef pair < pair < double, double > , pair < int , int > > WHAT_A_MAD_TYPE1111;
typedef WHAT_A_MAD_TYPE1111 my;

bool my_compare ( my & A, my & B )
{
   return true;
}

int main()
{
   vector < my > sorted;
   sort( sorted.begin(), sorted.end(), my_compare );
   return 0;
}

В 2005 студии же компилируется нормально.

Компилятор сообщает нам следующее:
