We can't assume that every architecture will have a 64-bit integer.
For that reason, and for the simple fact that if we are going to go to
the trouble of doing this, we might as well go all the way :), I think
we should use gmp's multiple precision integers. Then, it will work on
all architectures, and we can say that gnucash can support values of
arbitrary size.
