Given that the context is this: if (count >= 0) { /* Verify that snprintf() has NUL-terminated its result. */ if (count < maxlen && ((TCHAR_T *) (result + length)) [count] != '\0') abort (); wouldn't it be better to send the GCC maintainers a bug report? Since maxlen is unsigned, and since it is obvious to the compiler that count is nonnegative, there is no reason for a sign-compare warning here.
