Yeah, I found a program in about 10 seconds too. I just couldn't get it 
to *run*...

After going through about three pages of adverts with a "click here to 
start your download" burried within them, I gave up.

About half way down that page there's a captcha box and a download button.
Here's your dll.

  Why would it be obsolete? What would you suggest as an alternative?
It's still widely used in the unix world.

  I really can't understand why precisely cygwin is used to port unix
programs to Windows. Cygwin binaries rely on a bunch of dlls nobody has.

  mingw, on the other hand, is a cross-compiler which creates native
Windows binaries (both command-line and GUI'd) which do not require any
dll which a basic standard Windows installation wouldn't have.

  (The "cross-compiler" part means that you can, for example, compile a
Windows binary directly from linux. You don't even need Windows to be
in your computer at all.)

  Yes, mingw does not have all the posix and unix libraries that cygwin
has, but a pretty wide range of applications can be compiled with it
directly. I have never tried, but I assume tar could well be one of those.
(OTOH file stats might present a problem if mingw doesn't support them.)

Because it was invented several decades before I was even born?

Oh, mind you, that same statement applies to Unix, and that's still with 
us...

> What would you suggest as an alternative?

Actually, if you stop and think about this, there aren't any really good 
alternatives that are actually widely supported.

I have no idea.

  Computers were invented several decades before you were born. Are they
obsolete?

  If I use an alternative, 7zip is good enough for me. Usually compresses
better than tar+bzip2 too.

Nobody uses computers that were designed 40 years ago. They use 
computers that were designed maybe 3 years ago. Tar has been unchanged 
for a hell of a long time. That makes it either antiquated or 
increadibly well-designed, depending on how you look at it.

Likewise. However, 7zip is not (yet) nearly so widely available as 
PK-Zip or any of the Unix flavours of compressed Tar files.

star. :-)

Incidentally, the reason Zip is so widespread while lha, rar, etc are 
not, is the source for zip was given away with the license that you 
could create derivative works ONLY on the condition that it would not 
create files other versions could not read. Hence, zip became an 
exchange format, while the rest were striving to add another 2% or 3% 
compression ratios.

Which just goes to show that nobody really uses all the new ACLs and 
other permission stuff.

Because cigwin also supplies a shell and sym links and stuff like that, 
and as long as that's what you want under Windows, you might as well 
compile stuff using it. I.e., people use cygwin not because they want to 
port unix programs to windows, but because they want unix on their 
windows and incidentally they're porting this program. And hey, "it 
works for me."


FWIW, the key term to search on seems to be "win32". A native port of 
GNU stuff always seems to have the phrase "win32" somewhere in the name. 
SourceForge tends to be a good place to pick up stuff like diff and tar 
and so on.

  Ever notice how people in a zombie movie never already know how to

  who has reanimated from the dead in a secret viral weapons lab,
  and how many do you think already know you need a head-shot?

How about incredibly well designed and tested like most *nix utilities

I've never had a problem running cygwin as long as you run the cygwin 
installer from cygwin.org.  That includes everything you need and even 
resolves the dependencies so you can select the tar & gzip executables 
only and it'll install what it needs.

What I don't understand is why people distribute an executable for cygwin 
without mentioning "you need cygwin to run this" and a link to the site.

That's not entirely true...

http://www.atarimagazines.com/compute/issue132/92_Space_shuttle_techno.php

I had looked for a more current example, but I did recall that the 
shuttle flight computers were based on core memory technologies that were 
decades old.

Your statement above is kinda like saying "nobody uses hydraulic systems 
in avionics any more - it's all fly-by-wire now", which is also untrue.
