--- Comment #8 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Ed Smith-Rowland from comment #7) > g++ is working as intended. Thanks a lot for the investigation. Do you think the error message: "unable to find numeric literal operator" could additionally point out that -fext-numeric-literals or -std=gnu++11 would allow the code to work, for suffixes for which that is the case? That would have saved you a lot of investigation time ;-)
