whether to include files. Include <sys/param.h> if
HAVE_SYS_PARAM_H (not HAVE_SYSCTL).
(main) [defined __POWERPC__]: Add a kludge to work around a
Mac OS X bug, so that uname -p defaults to "powerpc" if
sysctl ((int[]) {CTL_HW, HW_MACHINE_ARCH}, 2, buffer, &bufsize, 0, 0)
fails. Problem reported by Petter Reinholdtsen in:
http://lists.gnu.org/archive/html/bug-gnu-utils/2003-02/msg00201.html
main): Use bool for booleans.
(writeline, check_file): Use uintmax_t for line counts.
(check_file): Check for and report line number overflow,
when that matters.
Include quote.h, xstrndup.h.
(TAB_STOP_SENTINEL): Increase from INT_MAX to INTMAX_MAX.
(convert_entire_line, have_read_stdin, parse_tabstops, next_file,
unexpand, main):
Use bool for booleans.
(tab_size, tab_list, add_tabstop, validate_tabstops, unexpand):
Use uintmax_t for column counts.
(first_free_tab, validate_tabstops, unexpand): Use size_t for sizes.
(add_tabstop, parse_tabstops, main): Don't reserve UINTMAX_MAX
as a tab stop.
(parse_tabstops): Don't use ISBLANK on possibly-signed char.
Detect overflow in tab stop string.
(next_file, main): Use EXIT_FAILURE/EXIT_SUCCESS instead of 1/0.
(unexpand): Concatenate input files the same way expand does.
(have_read_stdin, count_items, scan_zeros, detect_loop,
recurse_tree, walk_tree, tsort, main):
Use bool for booleans.
(exit_status): Remove.
(tsort): Return a success flag instead of storing into a global.
(main): Use it.
Remove. All uses replaced by C99 boolean primitives.
(TEST_TRUE, TEST_FALSE): New constants, for readability.
(test_unop, binop, unary_operator, binary_operator, two_arguments,
three_arguments, posixtest, expr, term, and, or, is_int, age_of,
one_argument, main): Use bool for booleans.
(advance, unary_advance): Now inline procedures rather than a macros.
(is_int): Renamed from isint, to avoid namespace clash with ctype.h.
(term, and, or): When it's easy, loop instead of recursing.
(term): Avoid integer overflow if there are INT_MAX-3 args (!).
(binary_operator, unary_operator): Simplify by systematically rewriting
true==FOO to FOO (where FOO is a boolean).
(unary_operator): Don't consider a file to be a regular file
merely because its mode&S_IFMT is zero. Just use S_ISREG.
Remove unnecessary casts. Remove ifdefs for things like
S_ISSOCK that are no longer needed, since stat-macros.h always
defines them now.
tac_stdin, tac_stdin_to_mem, main): Use bool for booleans.
(match_length, G_buffer_size, tac_seekable, main): Use size_t for sizes.
(tac_seekable): Use ptrdiff_t for pointer subtraction.
Report an error if the result is out of range.

calculations.
(main): Remove unnecessary casts.
the callee doesn't have to count 'em. All callers changed.
Don't allocate more space for the arg vector than we'll need.
Use memcpy to copy the args rather than rolling our own loop.
Use size_t for sizes.
(fast_startup, simulate_login, change_environment, log_su,
correct_password, restricted_shell, main): Use bool for booleans.
(longopts): Don't assume change_environment is an int.
Use NULL, not 0, for pointers.
(xsetenv): New function, replacing xputenv and concat.
All callers changed.
(elements): Remove; no longer needed.
(log_su, correct_passwd, main): Prefer !x to x==NULL.
(log_su): 2 -> STDERR_FILENO.
(modify_environment, main): Don't assume that getenv's returned value
has an indefinite lifetime.
(modify_environment): Allocate a larger environ.
(main): Remove an impossible 'case 0'; if it happens now, it'll
get diagnosed. Don't assume getpwnam results outlive endpwent.
Check for null or empty pw_name, pw_dir and for null pw_passwd.
(_POSIX_VDISABLE): Remove unnecessary cast.
(struct control_info, visible): Use cc_t for control chars.
(struct control_info): Use size_t for sizes.
(recover_mode, set_mode, display_speed, display_window_size,
valid_options, main, display_changed):
Use bool for booleans.
(integer_arg): Return unsigned long int, not long int.
Accept new max arg; all callers changed, to specify a maximum
value for integer parameters instead of silently overflowing.
(wrap): Do not overrun the stack buffer if the output contains
more than 1024 bytes. Instead, malloc a buffer.
(main): Remove a "what is this?!?" FIXME. Nobody knows what it is.
Remove unnecessary casts.
(set_control_char): Allow int values only up to cc_t range.
(screen_columns): Don't reject INT_MAX.
(display_changed, display_all, display_speed, recover_mode):
Don't assume cc_t fits in int.
unchecked integer overflows in this file.
(gnu_extensions, auto_reference, input_reference, right_reference,
ignore_case, initialize_regex, fix_output_parameters,
output_one_roff_line, output_one_text_line, output_one_dumb_line, main):
Use bool for booleans.
(SKIP_SOMETHING, compare_words, digest_break_file,
find_occurs_in_text, fix_output_parameters):
Use to_uchar instead of a caset.
(print_field): Rewrite to avoid cast.
(print_statfs): Print various gotta-be-nonnegative values using
unsigned long int, not long int or int.
(do_statfs, do_stat): Return a boolean success flag.
(do_stat, main): Use bool for booleans.
constant. Do not assume PRIdMAX etc. are strings of length 3 or
less.
(struct tspec): Use it. fmt_string is now an array, not
a pointer, as there's little point to the indirection here.
(struct tspec, flag_dump_strings,
traditional, flag_pseudo_start, limit_bytes_to_format,
abbreviate_duplicate_blocks, have_read_stdin, simple_strtoul,
decode_one_format, open_next_file, check_and_close,
decode_format_string, skip, write_block, read_char, read_block,
parse_old_offset, dump, dump_strings, main):
Use bool for booleans.
(struct tspec): Use void *, not char *, for generic pointers.
(bytes_to_oct_digits, bytes_to_signed_dec_digits,
bytes_to_unsigned_dec_digits, bytes_to_hex_digits):
Use char, not unsigned int, since char suffices.
(print_s_char, print_char, print_s_short, print_short,
print_int, print_long, print_long_long, print_float,
print_double, print_long_double): Rewrite to avoid casts.
These now take void * arguments, instead of char *.
Use the same body for all functions, except for the choice
of type. Assume C89 to simplify handling of signed char.
(dump_hexl_mode_trailer, print_named_ascii, print_ascii):
Rewrite to avoid casts.
(print_named_ascii, print_ascii): Now takes void *, not char *.
(decode_one_format): Use int for printf field widths, not
unsigned int. Pass void * to subsidiary printers,
not char *. Simplify handling of floating-point formats
by factoring out common code dealing with precision and field width.
(decode_format_string): Avoid need for temporary copy of
each decoded struct tspec.
(get_lcm): Remove unnecessary cast.
(main): Fix bug where more than INT_MAX failed decodes were ignored.
(enum number_format): Remove.
(FORMAT_RIGHT_NOLZ, FORMAT_RIGHT_LZ, FORMAT_LEFT): Now strings,
not enum values.
(DEFAULT_SECTION_DELIMITERS): Now an array constant, not a macro.
(section_del): Now const.

Use intmax_t for line numbers.
(reset_numbers, have_read_stdin, build_type_arg, nl_file, main):
Use bool for booleans.

(print_lineno): Check for line number overflow.
(proc_text, main): Remove unnecessary cast.

Use bool for booleans.
(dir_defaulted): Remove; no longer needed.
(main): Use int to count files, since it suffices for argv.
Rewrite to avoid need for dir_defaulted.
(main, print_dir, gobble_file, get_link_name,
xstrcoll):
Set exit status to EXIT_SUCCES/EXIT_FAILURE rather than 0/1.
(decode_switches): Put back check for ws.ws_col <= SIZE_MAX.
Remove unnecessary cast to int. Use int instead of unsigned
int to count from 0 to 1.
(get_funky_string, print_type_indicator): Use char for bytes, not int.
(make_link_path): Use NULL for null pointers.
(quote_name): Use to_uchar instead of cast.

(ok): New var (inverted from old sense).
(print_user, print_group, print_full_info):
Print uids/gids with %lu, not %u.

returns -1.
(fold_file, main): Use bool for booleans.
(fold_file, main): Use size_t for sizes.
(main): Allow -w options up to SIZE_MAX - TAB_WIDTH - 1, instead
of prohibiting widths greater than INT_MAX.
