--- Comment #17 from Marek Polacek <mpolacek at gcc dot gnu.org> --- (In reply to Jens Gustedt from comment #16) > Here the situation is a bit more complicated, since __typeof__ is an > extension to C, so no DR will directly say something about this. I can look into this, but I think it's a GCC 6 material. > Do you want me to open a new bug for the observation that _Generic leads to > compiler specific results? Please do. I think we should have a bug specifically to address DR#423.
