What I have suggested is the simplest (requires less stuff to be 
implemented) way to solve the problem, adding just a single 
compile time constant. But I agree there are better ways to solve 
the same problem. I am asking for a specific way to solve this 
problem, but since some years I'd like some "good enough" way to 
solve it.
