OK, thanks for your quick answer. I don't see any either, but I could 
try to modify NSButtonCell.h locally to have this method public. Maybe 
I need more help.
Netherletheless, it doesn't explain why clang don't throw an error 
here. And I've got several warnings of this kind when compiling 
rik.theme. I suspect this is'nt the only private method that has be 
used is the rest of the code.
