I'd expect all these macros to be implemented in the do { ... } while (0) 
style, so that they do genuinely act as single statements when followed by 
';', and then to be followed by ';' at the sites where they are used (so 
avoiding editors messing up indentation at / after those sites), unless 
there is some reason that convention can't work here.
