It is comparing against MAX_NON_LFS which is defined as:
	((1UL<<31) - 1)

You can use the 64 bit system calls by
#define	_FILE_OFFSET_BITS	64
(At least that is what I deduce by reading bits of the kernel & some header files)
So all that you need to do is to recompile: ls, cat, ...
and you should not have any problems.

Please let us know how you get on :-)
