VC6 is pretty strange, I agree. In particular, it doesn't handle 
functions with non-type template parameters well. The following code 
should demonstrate the problem. (Hopefully I'm remembering the problem 
correctly -- I don't have VC6 installed on this machine.)

template<int I> void foo() { std::cout << I << '\n'; }

int main() {
   foo<1>();
   foo<2>();
   return 0;
}

If you must use VC6, avoid non-type template parameters for function 
templates.
