"(module) called, and it's not done yet" indicates a call to a routine
that has been stubbed. There shouldn't be any negative effects as long
as the routine is UNIX specific.

I haven't used tar that much. I haven't had any problems. I think
though I remember reading something someone else had sent, though.
Check the mail archives (URL listed below signature).

don't know. Haven't tried it.

As long as you execute tar within the text=binary directories then the
\r should not be a problem. Tar will then not add or subtract anything
from the file. If you execute tar from text!=binary directories, \r
will be removed and control z ends the file.
