Packed attribute doesn't work if it's at the end of struct declaration

This works:
```
struct __attribute__ ((packed)) foo
{
	char a;
	int b;
} ;
```

This doesn't:

```
struct bar
{
	char a;
	int b;
} __attribute__ ((packed));
```

Afaics, the packed attribute is totally missed if it's at the end of the declaration.
