No, not at all.  Tar is an extremely flexible and versatile program,
with many switches that completely change its behavior.  In addition,
there's some DJGPP-specific code in the ported Tar which makes
sophisticated use of several system calls.  These all should be tested
if you want to make sure Tar works on W2K.  When I did the port, I
made a point of designing a small test case for every command-line
switch and for every feature documented in the manual.  (That was in
addition to the Tar test suite, which is fairly easy to run.)

Examples of tricky features include: preservation of time stamps and
access attribute bits; support for hard and symbolic links in the
archive created on a Unix system; special handling of files whose
names are reserved on DOS/Windows, like prn.txt or aux.c; the feature
whereby Tar excludes the archive from files being put into the same
archive when you say something like "tar cf foo.tar *"; comparison of
time stamps and mode bits in the archive with those on disk, so that
"tar --diff" works as expected immediately after you untar, even
though time stamps have 2-sec granularity.  And that's just a list of
issues I have after 5 seconds of thought ;-)
