Hello!

branch stable/13

git pull

just an hour ago

done buildworld

then  trying to

make buildkernel


and get

/usr/src/sys/kern/vfs_cache.c:5188:9: error: unused variable 'nc_flag' 
[-Werror,-Wunused-variable]
         u_char nc_flag __diagused;
                ^

I tried it yesterday - the same result, pulled again today and it is 
still the same

Is it a problem on my side or in the source and i just need to wait and 
pull again?
