As I see it, tar is assuming the j:/foobar is a relative path since the string
doesn't begin with /.  This causes the prefix /cygdrive/l/foo to be added to
make the path absolute.

If you:
   mkdir /j
   mount -b j:/ /j
   tar -C /j/foobar
then tar will see the string beginning with / and not make the false assumption
that the path isn't absolute.

The other option is to modify tar and submit the patches to
cygwin-apps@soures.redhat.com for consideration.

Cheers,
