Sergei Trofimovich 03e96250de dc3dd: fix for gcc-15 ...

Without the chnage the build fails as https://hydra.nixos.org/build/326967790:

```
In file included from argmatch.c:22:
argmatch.c: In function '__argmatch_die':
./config.h:8:22: error: too many arguments to function 'usage'; expected 0, have 1
    8 | #define ARGMATCH_DIE usage (1)
      |                      ^~~~~  ~
```

Work it around by falling back to pre-c23 standard.
