[Bug c/33024] gcc allows negatively-sized arrays

Consider:

main() {
  int x[0xFFFFFFFD];
}

fails to compile (array too large).

main() {
  int y = 0xFFFFFFFD;
  int x[y];
}

does compile.  Somewhere, your error checking (or lack thereof) for VLAs is
broken.  Unless I have just successfully allocated an array that is two bytes
shy of my entire virtual memory address space on a 32-bit architecture.
