--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- From https://gcc.gnu.org/bugzilla/show_bug.cgi?id=17654#c7 : That way at present is to use the C++ compiler, if you want the C++ const-correctness rules. Such a change was proposed for C99 in <http://www.open-std.org/JTC1/SC22/WG14/www/docs/n754.htm>. I do not know why it was not adopted although the impression I get is that it was proposed too late in the process and there wasn't enough time at the relevant meeting. I would suggest it might be worth proposing such a change again when features for C1x are under consideration in some years' time; C++ provides the prior art. So there are two points in this bug report. One add the extension to GCC and the other is fix the C standard. We are not going to accept it as an extension I don't think though. So you should see what is going on the C standard side of things.
