Actually my problem here is that I don't know how to express 
64 bit constants for MSVC.  The "LL" (long long) postfix does not
work.  Anyone know how to do this right?

But the version of toVector() that returns a non-const result does not
really affect the object is invoked on, so conceptually the method should
still be const even if the result isn't.
