The one user in particular who is testing this for me
claims that with the --force-local, tar is running to
completion but the tar file it's creating is zero length.
Sounds doubtful to me, but I haven't gotten any more 
information from him yet to figure out what's going on ...

Thanks again for your time.

In my Cygwin environment, "tar -cf C:/temp/foo.tar ." does not work;
I get an error about C being a hostname.  Looking at the tar code,
this is what I'd expect.  The comment in the code is

/* A filename is remote if it contains a colon not preceded by a slash,
   to take care of `/:/' which is a shorthand for `/.../<CELL-NAME>/fs'
   on machines running OSF's Distributing Computing Environment (DCE) and
   Distributed File System (DFS).  However, when --force-local, a
   filename is never remote.  */

I don't think the problem your non-Cygwin users are having has
anything to do with Cygwin, and I'm mystified as to why it works
correctly for you.  Are you using the same version of tar and the
cygwin DLL as your "non-Cygwin" users?

As you guessed, provide the --force-local switch.  Alternatively,
download the tar source, patch rmt.h to ignore remote paths, and
recompile.
