OK, a style warning seems reasonable.

I will check which compilers already issue such a style warning, and  
only include the warning for implementations that don't do this. If  
there is a common way of disabling such style warnings, I will try to  
integrate that as well, hopefully in a uniform way.

I'm not sure if I would want that. I think the right way is to use a  
global variable, a symbol macro, or an entry in *features*. I will  
check what is best.


Thanks a lot for the feedback!
