Zero-length arrays

[Richard Kenner]

What *precisely*, are the semantics of this feature.  Consider the following:

struct foo {int a; int x[0]; int y;} xyz = {1, {2, 3, 4}, 5};

int
sub1 (struct foo *p)
{
  return p->y;
}

This compiles with no errors with the current tree and XYZ contains in
memory the integers 1 through 5 as consecutive words.

But sub1 would return 2 when passsed &xyz, not the correct value of 5.

Of course there's no way to support returning the proper value here, so I
think the initializer should produce an error message.
