(name_gather): Handle trailing -C option correctly.
(addname): use memcpy, not strncpy, to copy a string of known length.
(name_match): Handle trailing -C option correctly.
Propagate -C option to following files.
Simplify matching code.
(name_scan): Simplify matching code.
(long_options, usage, main): -y is now -I (for --bzip).
(usage): Fix misspelling.
(OPTION_STRING): -y is now -I.
(decode_options): Use -1, not EOF, for getopt_long result.
Fix typo when invoking xstrtoumax: look for LONGINT_OK, not LONG_MAX.
Handle operands after any "--" argument.
(main): Report any output errors.
(<stdio.h>): Include only if testing.
(ISUPPER): Remove.
(ISLOWER): New macro.
(<string.h>): Include if HAVE_STRING_H, not USG.
(bcopy): Remove.
(yymaxdepth, ..., yycheck): Don't bother to redefine, since we can assume
bison.
(EPOCH_YEAR): Renamed from EPOCH.
(table): Renamed from TABLE.
(meridian): Now an anonymous enum.
(struct parser_control): New type.
(YYLEX_PARAM, YYPARSE_PARAM, YYSTYPE): New macros.
(yyInput, ..., yyRelYear): Migrated into struct parser_control.
(%pure_parser): Added, so that the parser is pure.
(%union): Removed; the type is now just plain int.
All %type directives removed.
(tLOCAL_ZONE): New %token.
(month_day_table): Renamed from MonthDayTable.
(gmtime, localtime, mktime, time): Declare only if not defined.
(meridian_table): New table.
(dst_table): New table.
(units_table): renamed from UnitsTable.
(relative_time_table): Renamed from OtherTable.
(time_zone_table): Renamed from TimezoneTable. Modernized.
(military_table): Renamed from MilitaryTable.
(to_hour): Renamed from ToHour.
(to_year): Renamed from ToYear.
(lookup_zone): New function.
(LookupWord): Renamed from lookup_word. Use lookup_zone for time zones.
(yylex): Now reentrant. All callers changed.
(get_date): Add support for local time zone abbreviations.
Make it reentrant.
(name_gather): Handle `-C x -C y' correctly.
Do not rely on addname to handle -C.
(addname): New CHANGE_DIR parameter.
Remove ugly calls to getcwd; no longer needed now that we have save-cwd.
(name_match): Use chdir_from_initial_wd, not chdir.
(name_from_list): Likewise.
(isotime): Now takes time_t, not time_t *. Report the decimal values
of times that can't be broken down.
(print_header): Don't assume that major and minor device numbers can
fit into uintmax_t.
(read_header): Fix computation of signed checksums on machines where
char is unsigned.
Do not consider a block to be zero unless all its bytes are zero,
even the checksum bytes. Do not attempt to parse the checksum of
a zero block. Fix memory leak with long names and links.
(from_chars): Accommodate a buggy tar that outputs leading NUL
if the previous field overflows.
(skip_extended_headers): Don't assume find_next_block yields nonnull.
(create_archive): Check for excluded names when doing incremental
pass through directory.
(dump_file): Do not dump old files explicitly given on command line
when using --listed-incremental. Do not strip ./ from front of file names.
Don't assume years fit into four digits.
Don't append trailing newline.
(print_header): Report ??? if localtime returns null;
Don't assume years fit into four digits.
