In the lint tests (which don't have a C preprocessor available), I use the following typedefs to get fixed-width integer types: typedef signed char int8_t; typedef short int16_t; typedef int int32_t; typedef long long int64_t; These types are the same on all platforms supported by lint, and I guess by NetBSD as a whole. I particularly avoid the types 'long' and 'long double', as they vary between the platforms. Curiously, intmax_t is a 64-bit type even on amd64, where __int128_t is also available, but I don't use that because that type is not predefined. Roland
