This is done in many places in the source. 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.

Bye,
Alexander.
