An array is implicitly (without the option to change it) indexed by
type `int'. Not `unsigned int', it's `int' -- because negative
indices are explicitly allowed (e.g. to access the previous array
element through a pointer like "a[-1]").
I'm not quite sure why GCC doesn't accept more than __INT_MAX__
*bytes* (as opposed to array elements); perhaps it internally aliases
everything to bytes.
