Okay...

Just so we don't get into each other's way, what I'm working on is improving 
the output of c_client.py so that the headers are readable and look nice. In 
addition, I'm preparing them so that you can get even nicer docs using 
doxygen. As far as the generated code or the declarations are concerned, I'm 
not going to touch those.

Yes, it's XKB where I noticed this useless error message. I'd also be happy to 
test that our changes don't conflict and merge properly. Otherwise, I'm gone 
over the weekend, so don't expect anything then.

Cheers!
