I wonder if the logic is (and was) sensible here. We assume that every non-__GNUC__ and non-_MSC_VER compiler on Windows requires the correction. Wouldn't it make sense to not assume requiring the correction unless we know the compiler has this bug? That is, shouldn't this better say

#if defined(WIN32) && (defined(__GNUC__) && __GNUC__ < 4) || (defined(_MSC_VER) && _MSC_VER < 1900)) #define SNPRINTF_SIZE_CORR 1 #else #define SNPRINTF_SIZE_CORR 0
