Big file strategy for star:
According to Posix 1003.1-1988, a 12 byte numeric field contains
11 octal digits and a space or a null.

	1)	Use unsigned 33 bit values conforming to Posix
		to allow 8 GB Filesize.

	2)	Set the top bit of theleftmost byte in the field
		and use base '256' digits to allow 95 bit values inside
		12 byte fields and 63 bit values inside 8 byte fields.

	3)	Use POSIX.1-2001 extended headers to have values
		without any limit.

	Files in type 2) and 3) will not be extractable with
	other tar implementations. Any files 'behind' such a file
	cannot be accessed.

	Files of type 1) may be extractable with other implementations.
