I tried a different version in gcc 3.0.3 and I think it works find.

The modified code is:

________________________________________
int main(int argc, char* argv[])
{
    std::cout
    << typeid(trait<int>::t1).name()
    << std::endl
    << typeid(trait1<int,1>).name()
    << std::endl
    << typeid(trait1<int,0>).name()
    << std::endl
    << trait<int>::value
    << std::endl
    ;
    return 0;
}
________________________________________

and the output is:
________________________________________
6trait1IiLi1EE
6trait1IiLi1EE
6trait1IiLi0EE
1
