Confirmed. Reduced slightly:
```
struct s1 {
int f1;
};
struct s2 {
int f2;
};
struct s1 f(struct s2 *);
struct s1 {
int f1;
};
struct s2 {
int f2;
};
struct s1 f(struct s2 *);
```
I think this is valid due to change in C23 tag compability.
https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3003.pdf .
Clang does not implement the C23 tag compatibility rules yet.
