sandra at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sandra at gcc dot gnu.org --- Comment #2 from sandra at gcc dot gnu.org --- This section of the manual also needs to be updated to talk about -fext-numeric-literals in C++ and the changes from PR117029, and maybe other changes as well. As it stands now I'm pretty confused about what is accepted with the different -std= options and how including/not including the standard header file affects that. :-(
