It seems like you've enabled large file support in busybox, but your libc 
doesn't have it.  (I'm guessing you're using uClibc and you've disabled large 
file support?)

Possibly what we should do now that we've got platform.h is just detect 
whether or not it's there and enable the CONFIG option behind the scenes.  
(Then if you disable long file support in uClibc, busybox builds without it 
but otherwise uses it...)

Joy.

Sigh, the classic nuxi problem.

I'll take a look this evening...

Yup.  Should be easy enough to fix, though...
