Remove old NeXT dirent problems, or AIX valloc problems.
Remove old union wait advice, and old %lld advice.
Remove advice about FreeBSD 2.1.7, ISC 4.1mu, Ultrix `make'.
Use chdir_do to change into directory.
Use deref_stat instead of stat.
Use add_avoided_name to mark names to be avoided; the old method of
setting a bit with the name caused all descendants of that name to
be avoided, in some circumstances.
(time): Declare if not defined.
(confirm): Don't read past EOF.
(long_options, usage): Add --no-same-owner, --no-same-permissions.
(main): Use clock_gettime if available.

(base64_map): Use UCHAR_MAX for size, not less-clear (unsigned char) -1.

as getting time can cause duplicate diagnostics if bogus.
Remove "Hmm, " from diagnostic.
Use "Skipping to next header" uniformly.
(from_header): Renamed from from_chars. All uses changed.
Allow different forms for unportable 2's complement numbers.
Don't check for extended forms when parsing checksums.
Parse base-256 output.

(to_chars): Use base 256, not base 64, for huge values.
(mode_to_chars): Don't use two's complement in GNU format or POSIX format.
(dump_file): Interchange last two arguments. If TOP_LEVEL is negative,
it means we have an incremental dump where we don't know whether this
is a top-level call.
Use deref_stat instead of statx / stat / lstat.
Cast result of alloca.
Check for dates if 0 < top_level, not if listed_incremental_option.
Move multiple-link check after directory check.
Do not dump avoided names.
Dump hard links to symbolic names as links, not as separate symbolic links.
start_header cannot return a null pointer, so don't test for it.
Likewise for find_next_block.
(time): No need to declare.
(now): Remove variable.
(extr_init): Don't initialize `now'.
Increment same_permissions_option and same_owner_option if we_are_root
is nonzero; this supports the new --no-same-owner option.
(set_stat): Use start_time instead of `now'.
(print_total_written): Also print human-readable byte count, and bytes/s.
(open_archive, flush_write): Use start_time, not current time.
(flush_read): Report about garbage bytes ignored at end of archive,
but act on non-garbage bytes (instead of ignoring them).
(new_volume): Use WARN for warnings.
(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.

(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.
