So which yacc parser do you use? bison?
Anyway, I did not manage to reproduce the issue. My guess is that it  
came from a buggy yacc parser, because the problem only appeared when  
processing gram.y. So I don't think it's useful to apply this patch  
at this point. Let's check if in the future someone reports a similar  
problem.

No, I do not have this issue (tested on a 2.6.21.3 patched kernel,  
and on the 2.6.22.1 GIT kernel). On both kernels it always succeeds  
to install the policy. Tell me if you need more tests or information  
from me.
