With revision 214400 we have the C++14 value of __cplusplus set to the
correct value of 201402L (from 201300L).
It occurs to me: instead of having to remember every time those numbers,
couldn't we predefine, for example:

     __cplusplus_98
     __cplusplus_11
     __cplusplus_14

with the correct values of course?!?
But won't this lead to portability trouble in the future when people see
those macros and start using them in their own code, breaking
compilation with older or non-g++ compilers?
Well, this can happen for any GNU predefined macro... What can I say, I tried to help ;) As a last resort we can maybe define the macros in bits/c++config...
