--- Comment #9 from Jonathan Wakely <redi at gcc dot gnu.org> --- Created attachment 65863 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=65863&action=edit Make libstdc++ configure check for memrchr Does this fix it? If it fails the same way for another function, we can check for that too, but this might be enough.
