@ -1925,10 +1925,13 @@ This macro is defined when the C++ compiler is in use. You can use
@code{__cplusplus} to test whether a header is compiled by a C compiler
or a C++ compiler. This macro is similar to @code{__STDC_VERSION__}, in
that it expands to a version number. Depending on the language standard
selected, the value of the macro is @code{199711L}, as mandated by the
1998 C++ standard; @code{201103L}, per the 2011 C++ standard; an
unspecified value strictly larger than @code{201103L} for the experimental
languages enabled by @option{-std=c++1y} and @option{-std=gnu++1y}.
