The idea is to black list platforms that don't do %zu and there is no way to do that without breaking cross-compilation. It is still preferable to use that if it is available, e.g. to help format string checks. > I still don't understand why autoconf is passing C pre-processor > directives down. > > #if sizeof(size_t) == sizeof(int) > ... > #elif sizeof(size_t) == sizeof(long) > ... > #endif > > directly in the code is much more readable. Doesn't work as the preprocessor doesn't know what sizeof(size_t) is. The macros are pre-computed similar to what genassym is doing for the NetBSD kernel build. Joerg
