I take that back, incomplete types are invalid here as long as you don't use
the function. So confirmed.
Here is a short testcase:
enum name func(void);
enum name { val = 1} __attribute__ ((__packed__));
enum name1 { val1 = 1 } __attribute__((__packed__));
int f[(sizeof (enum name1) == sizeof (enum name))?1:-1];
--- CUT ---
The above one should compile without error.
