What's the compiler version you're using? I'm running gcc 5.4.0 and I
don't see this message. And I don't use any special CFLAGS. I've even
tried compiling on Fedora and still nothing.
Normal Fedora 24 on x86-64,
gcc version 6.2.1 20160916 (Red Hat 6.2.1-2) (GCC)

I've taken look at Jenkins and don't see this problem there either.

I think we can just initialize the opts_need_arg with const_opts_need_arg.
