Hi,

The following patch should fix this:

http://80386.nl/pub/nandfs-warns-6.txt

As of a couple of days ago, WARNS=6 requires that global variables
either have an external declaration or are marked static. As
newfs_nandfs only consists of a single C file, we can easily mark
these variables static. In this specific case it allowed the compiler
to find another peculiarity in the code, namely that the
seg_segsum_size variable is unused.

I'll commit this patch after I've done some testing.

Thanks,
