(combine with existing seconds-based), treat '-' as punctuation rather
than a negative number indicator (eliminates several special cases),
use a single list of special words instead of several separate lists,
use table-driven abbreviation logic (eliminate duplicate word entries
and special-case abbreviation and plural handling). The result is
shorter, simpler (judging from comments, earlier maintainers didn't
understand the special handling for "negative years"), handles more
cases (e.g., "tu" is now a recognized abbreviation for "tuesday",
"3rd" is now equivalent to "third") and it has 2 fewer shift/reduce
conflicts.
particular, acl support is no longer enabled on FreeBSD 4, acl support
should be correctly enabled on Linux, dirent.d_namlen should be
correctly detected on platforms that support it.

extraction and creation. While I'm here, fix a bug reported by Garrett
Wollman: when stripping the leading '/' from the path "/", don't produce
an entry with an empty name; produce "." instead.
Also, reduce the WARNS level to 5 since different build environments
end up using different Yacc skeletons. The BSD one does not
predeclare yyparse, the FSF one does, so it's not really possible to
consistently enforce both -Wmissing-prototypes and -Wredundant-decls.

system one when it exists and use the fallback version
when it doesn't exist. Set the default for FreeBSD
to use the system version.
With this, bsdtar should now be quite portable.
In particular:
-W excl=text
fails because "excl" is a prefix of both "exclude" and "exclude-from". But,
-W exclude=text
is okay because it matches "exclude" exactly.

I'm here, change the man page to document "tar" rather than "bsdtar,"
update some comments about -l compatibility and fix a few grammar nits.
throw out the whole thing and stop tracking links entirely. That will
break all remaining hardlinks, but should free up enough memory to
let everything finish.
For -l, upset everyone by breaking it. Specifically, -l now produces
a lengthy error message that suggests --check-links (POSIX -l) or
--one-file-system (GNU -l) instead. However, if POSIXLY_CORRECT is set,
use the POSIX interpretation.
For -o, please everyone by making it work both ways:
* -xo uses POSIX behavior
* -co uses "almost GNU" behavior (as close as we can get until
libarchive implements a true V7 tar format)
