"16.8 Predefined macro names [cpp.predefined]
1 The following macro names shall be defined by the implementation:
__cplusplus
The name __cplusplus is defined to the value 201103L when compiling a
C++ translation unit.155
155) It is intended that future versions of this standard will replace
the value of this macro with a greater value. Non-conforming
compilers should use a value with at most five decimal digits."
