You have misread my post.  This is a simple matter and I hope we can 
resolve this quickly.

Notice that my post contains the text:

Notice the content inside the parenthesis.  I have added the constraints 
in order to make my if statements more readable.  But the if statemenst I 
posted are isomorphic to the ones you posted.

Yes, this is exactly the if statement I have been arguing.  You and I are 
in agreement as to what the GPL says.  Now the point I am making is that 
the following branch:

>         if (GPL code removed) then
>             return (fine)
>         else

Is of great significance.
