- But C and C++ are different languages (And my postmaster is not happy with
- my 30K/day new articles list even without my subscription to c.s.c). Maybe
- someone will be so kind as to review the arguments against it (I could not
- invent one). It would be very nice to have a type with a guaranteed range
- (I think that was the motivation of the grumbles here about __int64 some
- time ago). It may be needed even on 32-bit computers (how do you address
- sectors (and file positions) on the 9G Barracuda drive, for instance?).

- Best regards Genie

- PS. What about standard arbitrary precision integer class template
- wint_t<size_t bytes>, with the specialization using hardware long long if
- available? BTW, the constantly recurring question - is there the arbitrary
- precision int class somewhere?
