--- Comment #29 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to andyg1001 from comment #28) > Erm, am I the first to notice that this "solution" is broken? No, see https://gcc.gnu.org/ml/libstdc++/2016-09/msg00228.html > The os_defines.h include that undefines _GLIBCXX_HAVE_GETS is included > before _GLIBCXX_HAVE_GETS is (re)defined inside c++config.h. > > Therefore, _GLIBCXX_HAVE_GETS is still defined when we get to <cstdio>. > > Seems still to be broken even in trunk.
