-Werror errors on RELENG_8_0 world

[Dmitry Marakasov]

Hi!

I've just got a buildworld error on a recent RELENG_8_0:

There are some more, but it builds fine with NO_WERROR=1.

SVN logs show that code wasn't changed for a long time, so why
weren't these detected and fixed yet, or am I missing something and
this is a some local problem?
