--- Comment #2 from Harald van Dijk <harald at gigawatt dot nl> ---
Thanks for the pointer. That commit looks like it fixes a different issue: that
looks like it's about allowing
void operator""_u(const char *, __SIZE_TYPE__) { }
which was previously rejected. It does not actually fix the issue my testcase
demonstrates, it merely makes it so that my testcase no longer demonstrates my
issue. I'll attempt to come up with a different testcase.
