I just added some class templates that had declarations like: //======================================== template < intmax_t Value > struct whatever; //======================================== Afterwards, I was looking over some of the Boost.Integer headers and got curious about the BOOST_NO_INTEGRAL_INT64_T setting used within <boost/integer_traits.hpp>. I think we could add two typedefs to <boost/cstdint.hpp> //======================================== #if !defined(BOOST_NO_INT64_T) && defined(BOOST_NO_INTEGRAL_INT64_T) typedef signed long intmaxc_t; typedef unsigned long uintmaxc_t; #else typedef intmax_t intmaxc_t; typedef uintmax_t uintmaxc_t; #endif //======================================== Where "intmaxc_t" is the largest signed integer type that is suitable for integer constant expressions (like value-based template parameters) and "uintmaxc_t" is the unsigned equivalent. They should be the same as "intmax_t" and "uintmax_t" on non-broken compilers. I'd change my code to use the new types, to be safer. -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
