Well, unfortunately more problems with that:

$ star xvjf jake.ntfs.tar.bz2
x jake_winxp.ntfs 6292304384 bytes, 6162300 tape blocks
Segmentation fault

Extract the file up to 4335726080 bytes and then throws SEGFAULT.

That's with star: star 1.5a67 (i686-pc-linux-gnu).

I tried to compile the latest version (5a74) myself , but that fails with
------------------------------------------------------------------------------------------------------
/usr/src/linux/include/linux/percpu.h: In function '__alloc_percpu':
/usr/src/linux/include/linux/percpu.h:45: error: 'GFP_KERNEL' undeclared

/usr/src/linux/include/linux/percpu.h:45: error: (Each undeclared

during compile (using linux kernel headers 2.6.15/16).

Any more hints?
