--- Comment #1 from Marc Glisse <glisse at gcc dot gnu.org> ---
Same here (CXXFLAGS_FOR_TARGET="-O2 -g -flto -ffat-lto-objects" after a trivial
fix for PR 43538):

/data/repos/gcc/trunk/libstdc++-v3/src/c++98/ios_init.cc:56:33: warning: type
of 'buf_wcerr' does not match original declaration [enabled by default]
   extern stdio_filebuf<wchar_t> buf_wcerr;
                                 ^
/data/repos/gcc/trunk/libstdc++-v3/src/c++98/globals_io.cc:105:17: note:
previously declared here
   fake_wfilebuf buf_wcerr;
                 ^

etc.

Reassigning to libstdc++ because the warnings seem to say the truth.
