With -fsyntax-only GCC erroneously rejects the following array 'x' as having
non-constant size.  Its size should evaluate to 1.

int
bar (int v)
{
  int (*p)[v];
  int (*q)[2];

  static int x[sizeof(*(v ? p : q)) == 2 * sizeof (int)];

  return x[0];
}

I should add that switching p and q causes GCC to accept it.
