Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org, | |redi at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think that ctor is constexpr since https://wg21.link/N3471 Does that have some feature test macro? If not, should we use constexpr conditionally for C++14 and const otherwise?
