I have never fully understood what goal these sequential obesity-binges from ISO-C serve. Structure packing ? Nahh, nobody uses that. Big/Little Endian API ? Naah, nobody moves binary data between computers. Ohhh, but I know: Lets make a rival to the POSIX threads, we can do it much better and slightly incompatible, big market there I'm sure. What ? A "assert mutex is held" facility ? Why would you want that ? Just write perfect code to begin with! Bang! Bang!
