>Description:
When doing make MALLOC_PRODUCTION=yes buildworld, a compiler warning will be issued which halts compilation. The warning is issued because line 463 of head/sbin/fsck_ffs/fsutil.c uses "%ld" and "%lld", for variables of type time_t, which I think are of the type int in this case when compiling for armv6. 
>How-To-Repeat:
Following this guide to step 13 should do the trick:

>Fix:
Typecasting like this solved the problem:

printf("%21s:%8ld %2ld.%ld%% %8lld msec %2lld.%lld%%\n", buftype[i], (long)readcnt[i], (long) readcnt[i] * 100 / diskreads, (long) (readcnt[i] * 1000 / diskreads) % 10, (long long) msec, (long long) msec * 100 / totalmsec, (long long) (msec * 1000 / totalmsec) % 10);
