Thanks, for coreutils it'd be helpful to now whether there's a similar 
problem with chmod-related syscalls. If you compile and run the attached 
program on a file that you don't own (e.g., './a.out /'), does it 
incorrectly issue "Permission denied" instead of "Operation not 
permitted" diagnostics?
