The compiler seems to behave correctly WRT C99. However, when
presented with code that uses extensions the compiler behaves
inconsistently or erratically. If the compiler cannot do any-
thing useful with zero-sized arrays, it should reject them
completely. Only then can one reasonably fall back on C99 to
explain the behaviour of the compiler. However, since the
compiler accepts zero-sized arrays, it is already in violation
with C99 and one cannot use C99 as a basis to explain the
any behaviour of the compiler in the context of the non-compliant
construct. The creation of single-element array instead of
the declared zero-element array is downright broken.
