this is a bug in ac++ 0.9.3, which affects aspects that perform an 
introduction into a class, have code advice on join points in the same 
class, and include the header file of the class. Exactly, all these 
circumstances come together in ElementCounter2.

If you only want all examples to compile, downgrade to the 0.9.2 version 
of the ac++ compiler feature in your eclipse environment.

If you want a workaround that helps with ac++ 0.9.3, replace:

that(queue): before (util::Queue& queue) {    with
that("util::Queue") : before () { JoinPoint::That &queue = tjp->that();

If you use the JoinPoint-API and don't reference the type util:Queue 
anymore, you can delete the #include "queue.h". Then it will work again.

The bug is already fixed internally.

Sorry for this,
