It's a common way of writting a macro which is usable like a function (yes, this macro returns, so it doesn't _work_ like a function, but this is not the point). Usually this is used with macros which take arguments. You just can add a ';' after the use of the macro without having to remember if you need to do it, or if your compiler may moan because of an empty statement. Have a look into style(9), it also has to say something about it.
