--- Comment #7 from Eric Gallager <egallager at gcc dot gnu.org> --- Anyways my point about bringing up which standards stpcpy() is in is to remind people to keep portability concerns in mind when doing this change. Please check the gnulib docs on stpcpy() for specifics: https://www.gnu.org/software/gnulib/manual/html_node/stpcpy.html
