See the patches I posted on this thread
<https://groups.google.com/forum/#!topic/v8-users/TgJIIIWsy20>, you need to
add "-Wno-range-loop-construct" and maybe "-Wno-invalid-offsetof" to your
compilation flags if you're using clang.
The patches are for the 8.3 branch head, but the changes needed are about
the same.
