Yes, that is the solution for Anthony's problem. Most include files
used by LCL units have it but FPC libraries may not.
When the directive is set, Lazarus IDE always knows how to jump
between interface in Pascal unit and implementation in an include
file.
The {%...} directive is a comment in other contexts and can be used safely.

When a big Pascal unit is split into include files then an include
file is referred from one place only.
The directive is not meant for generic include files.

The original question about dynlibs remains. I understood with FPC 3.0
it is not needed but I could not compile without it.
This has nothing to do with cross-platform code. I am testing with
Xubuntu + GTK2 as the code is part of LCL-GTK2.
Actually I still have the RC1 version here:
 $ fpc
 Free Pascal Compiler version 3.0.0rc1 [2015/08/07] for x86_64
 ...
Could there be such a difference between RC1 and the release?
Anyway, I added dynlibs there. It is needed at least by FPC 2.6.4
which we still support for some time.
Ubuntu people, please test the Unity TTrayIcon feature. I have only
tested it does not break LCL-GTK2 in other systems. I will install
Ubuntu + Unity soon.
