Also, if the built-in strlen is or could be made constexpr then all thechar* ctors could be constexpr as well.
I think we'd need to make char_traits<char>::length() constexpr too,
and that's not allowed by the standard.

Shouldn't we have a macro _GLIBCXX_GNU_CONSTEXPR that expands to constexprwith -std=gnu++11 and to nothing with -std=c++11?
