We've talked about this problem off and on for years now, and I'm wondering if we can finally solve it. Many compilers supply built-in integer types beyond (unsigned) long int, but someone told me that there's no guarantee that those super-long types are suitable for use in a value-based template parameter. I'm wondering if we can develop typedefs, maybe in "boost/cstdint.hpp", that describe the largest suitable signed and unsigned built-in integer types that can be used as value-based template parameters. On basically-standard compilers, this would be "unsigned long" and "long". I'm thinking that we could default to boost::[u]intmax_t, and #case it for particular compilers after they choke on not being able to use "long long" or "__int64_t" in a template. (We could test in advance to minimize hardship.) -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
