extern int (*a)[];
void g(void) { a++; }
yields the diagnostics
t2.c: In function 'g':
t2.c:2: error: increment of pointer to unknown structure
t2.c:2: error: arithmetic on pointer to an incomplete type
This isn't a pointer to a structure, it's one to an array; and after giving the
first diagnostic, it's useless to go on and give the second as well.
