Re: [boost] [config] BOOST_STATIC_CONSTEXPR in C++11 vs C++14

Actually I think it's a lot simpler than this: when it was added, |BOOST_CONSTEXPR_OR_CONST did what it says, and what it's documented to do - namely declare something const or constexpr (which implied const at the time). Subsequently it's been broken by C++14 where constexpr no longer implies const.

I don't think that this is true; constexpr does imply const in C++14 for variables. It no longer implies const for member functions, but that's a separate matter.
