--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
It's not optional, it's a required feature in C++14 and later. Failing to
provide it is non-conforming, although GCC can be requested to be
non-conforming the same way with -fno-sized-deallocation. Using that, the s=
ame
error happens with GCC.

We should either disable __cpp_lib_generator when __cpp_sized_deallocation =
is
not defined, or change <generator> to not depend on it unconditionally.=
