I would normally agree with that. However, with poisoning on, the macro 
definitions still generate a warning. I don't want to give the user who uses 
all up-to-date features a whole bunch of new warnings just to point out 
deprecated items.

If you can figure out a way to have gcc to only give an error on *usage* of a 
symbol (and not also a warning on the #define) then I think we can certainly do 
what you suggested.
