Wrap #include wchar.h and wctype.h in #if. (build_range_exp): Add castings to strlen invocations. (build_collating_symbol): Restore the type of characters from "char" to "unsigned char", and supplement castings. (build_collating_symbol): Likewise. (build_equiv_class): Likewise. (build_charclass): Likewise. (seek_collating_symbol_entry): Likewise. (parse_bracket_exp): Likewise. (build_word_op): Supplement a casting.
