[Bug c/26581] incomplete (unsized) static array types cannot be completed

Thanks - I'd forgotten that 'static' declarations can be 
tentative definitions too.  But now I'm even more confused!
As I wrote, unsized arrays do one thing, undefined structs do another
(this is a "gcc fact" whatever its ANSI-legal status).

Consider this:
struct poo; /* declares an incomplete structure type, 6.7.2.3 para. 7 */
static struct poo thingy; /* a tentative definition, 6.9.2 para. 2 */
/* The structure type is still incomplete, 6.7.2.3 para. 3 */
/* any subsequent definition of struct poo is too late */

Shouldn't this now be flagged as an error, at least if '-pedantic'
is requested?

If I'm wrong again about this, I'll shut up...
