I installe this patch. It doesn't fix any bugs, except for the
undoubtedly only-theoretical porting bug of ws.ws_col > SIZE_MAX.
2004-08-02 Paul Eggert <address@hidden>
* src/ls.c (struct fileinfo, file_interesting,
extract_dirs_from_files, color_symlink_as_referent,
FILE_OR_LINK_MODE, sort_reverse, print_owner, print_group,
numeric_ids, print_block_size, dired, print_with_color,
check_symlink_color, print_inode, recursive, immediate_dirs,
all_files, really_all_files, qmark_funny_chars,
print_dir_name, format_needs_stat, format_needs_type, visit_dir,
main, decode_switches, parse_ls_color, print_dir, file_interesting,
gobble_file, make_link_path, basename_is_dot_or_dotdot,
extract_dirs_from_files, print_long_format):
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.
