No, I would use a 64-bit type to compute. If you have a deficient
compiler that does not support 64-bit integers, then you have trouble,
but so what? You could have equally asked to deal with numbers in the
range 2**44, and then you would have needed a larger type anyway.
These days, all compilers should support 64-bit integers.
