[IGSTK-Developers] Borland compiler and StateMachine macro

[Luis Ibanez]

Julien,

Another option is to drop the

            "private: "

Keyword inside the Macro, and stablish the
rules that:



A) the state machine macro must be the first
    on the class declarations


B) a "public, protected, private" must be
    placed just after the macro.



My only concern with this solution is that
we rely on developers to remember to do the
right thing...     but.. maybe that's good
enough given that we have the code reviews.



    Luis
