Everything Eric said about copying the DLLs being unsupported, the
old version of tar, and about using Win32 paths stands. Expanding on
that, however, you seem to have omitted the --forcelocal option in your
two non-working examples, which may cause tar to look at a remote
filesystem (and time out, I guess).
I would first try POSIX paths. If that doesn't help, please look at
<http://cygwin.com/problems.html> for guidelines on reporting Cygwin
problems. In particular, you might want to clarify the "Just does not see
to like stdin" part (i.e., what exactly happens?), and what the output
looks like for the first command (you *are* running "tar -cvf", after
all).
