I believe that the C standard defines that NULL has to become available through (at least) stdio.h. Though wikipedia may not always be authoritative, I will use it as an excuse now: http://en.wikipedia.org/wiki/Stdio.h So if #include <stddef.h> makes NULL available, good for glibc, but it may not satisfy certain implementations. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
