With gcc 4.8 the compilation goes fine with and without this CL, after gcc 4.9.2
it eases our life. Trybot results suggest it must be ok with all the supported
compilers but ARM guys, please take a look.

Fine by me. That warning fires quite a lot. Sometimes it _is_ useful, but rarely
in practice.

LGTM (if ARM is fine with this).

lgtm. +Andy, fyi. Please re-run the failing trybots, they appear unrelated to
me.
