--- Comment #23 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Giuseppe Ottaviano from comment #22) > Yes I referred to the trailing return type.

Is r225244 > already included in a GCC release? No, only on trunk. It depends on the additions in r225242, so to use the new alloc_traits.h you would only need the new code in https://gcc.gnu.org/viewcvs/gcc/trunk/libstdc%2B%2B-v3/include/std/type_traits?r1=225242&r2=225241&pathrev=225242 (which could be added to the top of alloc_traits.h just in order to test, if that's easier).
