The gcc source however +has not been updated to include that which has lead to a mismatch. + +In practice, this hasn't been an issue for two reasons: +(1) Before gcc-5, the default standard was (gnu) C89, and gcc does not +warn or throw an error in this mode. +(2) Starting with gcc-4.8, the compiler driver used to build gcc was +changed to C++, and g++ does not warn or throw an error in this mode. + +This error does show up though when using gcc-5 to build gcc-4.7 or +older as then the default is (gnu) C11 and the C compiler driver is +used.
