-support for the upcoming ISO C++ standard (200x).

+experimental support for the second ISO C++ standard (2011).
 
 The original ISO C++ standard was published as the ISO standard (ISO/IEC
 14882:1998) and amended by a Technical Corrigenda published in 2003
 (ISO/IEC 14882:2003). These standards are referred to as C++98 and
 C++03, respectively. GCC implements the majority of C++98 (@code{export}
 is a notable exception) and most of the changes in C++03.  To select
-this standard in GCC, use one of the options @option{-ansi} or
-@option{-std=c++98}; to obtain all the diagnostics required by the
-standard, you should also specify @option{-pedantic} (or

 @option{-pedantic-errors} if you want them to be errors rather than
 warnings).
 
-The ISO C++ committee is working on a new ISO C++ standard, dubbed
-C++0x, that is intended to be published by 2009. C++0x contains several
-changes to the C++ language, some of which have been implemented in an

-working paper for the C++0x standard; the latest working paper is

 By default, GCC provides some extensions to the C++ language; @xref{C++
 Dialect Options,Options Controlling C++ Dialect}.  Use of the
 @option{-std} option listed above will disable these extensions.  You
 may also select an extended version of the C++ language explicitly with
 @option{-std=gnu++98} (for C++98 with GNU extensions) or
-@option{-std=gnu++0x} (for C++0x with GNU extensions).  The default, if

 no C++ language dialect options are given, is @option{-std=gnu++98}.
