* ch-exp.c (parse_primval): Handle CARD, MAX, MIN.
(match_string_literal): Handle control sequence. (match_character_literal): Deto. * ch-lang.c (chill_printchar): Change formating of nonprintable characters from C'xx' to ^(num). (chill_printstr): Deto. (value_chill_card, value_chill_max_min): New functions to process Chill's CARD, MAX, MIN. (evaluate_subexp_chill): Process UNOP_CARD, UNOP_CHMAX, UNOP_CHMIN. * expression.h (exp_opcode): Add UNOP_CARD, UNOP_CHMAX, UNOP_CHMIN for Chill's CARD, MAX, MIN. * valarith.c (value_in): Add processing of TYPE_CODE_RANGE and change return type from builtin_type_int to builtin_type_chill_bool.
