The headers this pulls in use noexcept with newer boost, so -std=c++03
doesn't work anymore. Just remove it and use the compiler's default.

I bumped the majors since there's quite a bit of churn resulting from
this change and I'm not interested in spending time on reducing the
bumps to the strict minimum.

FreeBSD uses a compiler setting -std=c++11 so doesn't need this patch.
