* cppexp.c (LOGICAL): Delete macro.
(_cpp_parse_expr): Do not use UNARY for unary +. Implement ||
and && directly.
* cpphash.c (HASHSIZE): Increase to 4096.
(struct hashdummy): Add hash field.
(eq_HASHNODE): Compare unreduced hashes, then lengths, then
the string values using memcmp.
(cpp_lookup): Set dummy.hash.
