--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced further (a C++20 since C++20 expanded the use of auto to functions
rather than just lambdas but still invalid):
```
typedef int mytype;
void f(mytype auto... I) {}
```
Note without the variable argument auto, GCC rejects the code:
<source>:2:8: error: two or more data types in declaration of 'I'
2 | void f(mytype auto I) {}
| ^~~~~~
