Correction.  `lvalue', as the term is used in the dpANS, does not mean
`something that can appear on the LHS of an assignment'.  In fact arrays
*are* lvalues in ANSI C.

Lvalues include two flavors of things that cannot be assigned (arrays and
consts), and two flavors of things that have no address (bitfields and
registers).  A `register const' is neither addressible nor assignable, but
it's still an lvalue.
