--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Jacob McIntosh from comment #4) > It looks like this is supposed to be a c++1y/1z feature (post c++-14 > anyway)... and it looks like it's not implemented yet in gcc. Same errors > for me with -std=c++1y and also with -std=c++1z Have you tried the trunk instead?
