Patch to ensure reasonable cluster sizes

I can confirm this bug is still there in 1.0 and submit this patch which fixes
it for me. Linux reports the nfs rsize as the f_bsize value from fstatfs.
f_bsize ultimately becomes the cluster size. The linux behaviour is probably
reasonable. However, with tcp conected nfs the rsize can be very large
(defaults to 128k on fedora8) which is larger than the maximum cluster size of
any windows fs. There is no documentation I could find that says what the
largest cluster size windows (any version) accepts, but the fat32 file system
has a 16k maximum cluster size and the ntfs has a maximum cluster size of 4k
for nt4.0 and later.

A google shows that people have seen this message on windows systems (not wine)
installing onto smb filesystems as well.
