--- Comment #6 from Keith Thompson <Keith.S.Thompson at gmail dot com> --- Shall I submit a separate ticket against the documentation? "info gcc" for gcc-7.1.0 has the following description for -std=c=+98 and std=++03: 'c++98' 'c++03' The 1998 ISO C++ standard plus the 2003 technical corrigendum and some additional defect reports. Same as '-ansi' for C++ code. and this for -std=c++11 and -std=c++0x: 'c++11' 'c++0x' The 2011 ISO C++ standard plus amendments. The name 'c++0x' is deprecated. Both should mention DRs. (I question the policy of implementing DRs that have not been approved by the committee. As I understand it, the existence of a DR merely means that *someone* thinks there's a defect in the standard. Many DRs are eventually rejected.)
