I'm using WinZip, or some other non-POSIX client, and files are not
 being extracted properly!
     By default, "Archive::Tar" is in a completely POSIX-compatible mode,
     which uses the POSIX-specification of "tar" to store files. For
     paths greather than 100 characters, this is done using the "POSIX
     header prefix". Non-POSIX-compatible clients may not support this
     part of the specification, and may only support the "GNU Extended
     Header" functionality. To facilitate those clients, you can set the
     $Archive::Tar::DO_NOT_USE_PREFIX variable to "true". See the "GLOBAL
     VARIABLES" section for details on this variable.
