Can I be reasonably sure that if I use some sort of 64-bit integer in
Ada, that it will be represented by native 64-bit registers on a 64-bit
machine, and perhaps even more important, that it will be represented by
some very effecient double 32-bit registers scheme on a 32-bit processor?
For instance, with GNAT, will it be as fast to use Ada for this kind of
thing as it will be to use long long with GNU's C or C++ compiler?
