I compiled this code in VC7.1, and it did compile although with warnings.

But then I modified main to look like this:

int main()
{
SET(X, 10);
std::cout << CURRENT(X) << "\n";
std::cout << VALUE(X) << "\n";
SET(X, 15);
std::cout << CURRENT(X) << "\n";
std::cout << VALUE(X) << "\n";
SET(X, 20);
std::cout << CURRENT(X) << "\n";
std::cout << VALUE(X) << "\n";
SET(X, 15);
std::cout << CURRENT(X) << "\n";
std::cout << VALUE(X) << "\n";
}

the output was somewhat different than one would expect:

1
10
2
15
3
20
3    -- wrong
20  -- wrong

How do you handle this in your typeof implementation?  Do you reset it
somehow between typeofs?  Or do you start from the next available number?
