I do not know if this is already known but
if tar is invoked as:
  tar -cvf foobar.tar --name-prefix=c:/foo/  z:/bar
both path strings, c:/foo and z:/bar will be concatenated
together like this:
  foo/z:/bar
instead of:
  foo/bar
as it should be. From both path strings, the drive spec
and the leading slash should be removed before concatenating
them . If no name-prefix is given at all the drive spec and
first slash will be removed from
  z:/bar
in the correct way.
The patch below documents/fixes the issue.

Regards,
Guerrero, Juan Manuel
