By my reading of section 3.4, both of the following examples are
not legal:

/* 1 */
static int i = "abc"[2];

/* 2 */
static int a[5];
static int j = &a[3] - &a[2];

The second example, in particular, is interesting, since by my reading
K&R (first edition) allows it, and the pcc-based compiler on my Sun does
too.

Anyone feel these are legal?  Have I read the text wrong?
