Problem
    When I was making disk images for CD-R on my HDD,
        tar --tape-length=650000 -cv --file=/home/xxx/image.tar /archive-source
    I could not use any number for '--tape-length' option.

Patch
    It seems we can use only the value "LONG_MAX" for '--tape-length'.
    I'm not sure what intended to check at the line...,
    but " != " is wrong, I think.
