>Description:
1) printf() modifiers on LP64
2) warning "dereferencing type-punned pointer will break strict-aliasing rules"
I had to change cast (struct bucketlist *) to (void *) to shut up this warning
without much rewrite. *sigh
3) s/kvm_open/kvm_openfiles/;
when using kvm_open, kvm_nlist returns "No such file or directory".
that fixes this warning. I didn't find much difference umastat output.
