The circles are a problem again. And they will stay a problem. 
They are unnecessary and make it difficult to control the order of the
initialization and finalization sections. They make it harder to
understand code. All this makes the LCL a bad example for writing code. 
We are using mode objfpc to disallow Delphi ambiguities, but we don't
use any of the nice extensions (e.g. c operators, inline, exit(), ... )
of this mode. All this to give a good example for readable pascal code
(and some other more abstract reasons). But OTOH we use circles.
Also circles are not very helpful for smartlinking.
I don't mean the circle between the interfaces and the LCL, although
this can be broken rather easily as well.
I mean circles like: controls.pp needs menus.pp, for the only reason
that it needs TPopupMenu.

I don't want to ignore the old discussion, but I hope someday the LCL
will become an easy hierachy instead of the furball it is now.
