Compiling this code gives a warning. I expect no warning. GCC does not give a warning since version 13. It looks like the front end does not recognize that specifiers for exact-width types are allowed.
```C
#include <stdint.h>
#include <stdio.h>
int main(void) {
printf("%w64d\n", INT64_C(0));
return 0;
}
```
```
clang -Wall -std=c2x print.c
print.c:5:13: warning: invalid conversion specifier '6' [-Wformat-invalid-specifier]
5 | printf("%w64d\n", INT64_C(0));
| ~~^
```
My version is 18.0.0git 6452395561ea.
