--- Comment #7 from Christophe Lyon <clyon at gcc dot gnu.org> --- Looking at my build dir, I can see that libstdc++ build system makes symlinks to time_members.cc in the build dir. And in my case, all these links point to libstdc++-v3/config/locale/generic/time_members.cc, which does not have the offending code.
