But if this happens, it is bad coding. Programs do not need to use 64
bit variables just because they are available. They can just as well
keep using as small a variable as they really need.

Another issue is variable packing. The compiler might align small
variables on bigger limits (64 bit?), which would nullify the effort to
conserve memory.
