BTW, just to be clear for those on the list:

--use-ntvfs is gone by default, because we don't build it by default.
To re-enable it if you have a really important use case you use --with-
ntvfs-fileserver at configure time.

The main reason for that is so that when a security hole is found in
the NTVFS file server (as all C code is prone to), that we don't have
to make the NAS vendors and major linux distros upgrade their packages,
as the code won't be in their binaries. 

(However we would really like to know if that is really needed, as the
code will probably go away at some point).
