--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

It has nothing to do with aliases at all. All has to do with the copy attri=
bute
not copying the C++11/C23 attributes correctly.

Even the following C++ code incorrectly warns.

Like:
```
[[maybe_unused]] int foo(void);

[[gnu::copy(foo)]] extern __typeof__(foo) bar;

```=
