It's a constraint violation, because the constant expression
inside the brackets does not have a value greater than zero.

Perhaps you are looking for the "struct hack". In that case,
take a look at the FAQ, question 2.6.

Prescribed textbooks may well not mention this, since it is not
standard C. It doesn't seem to be mentioned in the FAQ either
(the struct hack section only covers char a[1]).

That was my point. If he read his textbook, he'd have known that the
above definition is invalid.
