You can always add some more misc template parameters:

void foo1() {
    struct unique_foo1_tag;
    cout
            << is_complete<incomplete, __LINE__, unique_foo1_tag>::value
            << is_complete<incomplete_template<0> , __LINE__,
unique_foo1_tag>::value
            << is_complete<incomplete_template<1> , __LINE__,
unique_foo1_tag>::value
            << is_complete<complete, __LINE__, unique_foo1_tag>::value
            << is_complete<complete_abstract, __LINE__, unique_foo1_tag>::value
            << endl;
}

And you can also use __COUNTER__ on MSVC.
