That's one of the few packages where I'm not going to patch that out.

As per https://wiki.gentoo.org/wiki/Project:Toolchain/Support_policies building of two major versions older GCC is intended to be supported, even with -Werror used.
I'd reopen this bug for that, but... there is no error, it built fine and the log contains no errors. If it actually fails to build with 1 or 2 major versions newer GCC, then report that, not -Werror in case of GCC (-Werror is wrong in most other packages still and probably worth a bug report).
