[Samba] Samba as a portable userland FS basis?

a quick ./configure test on Cygwin results in:

...
checking whether to use included popt... ./popt
checking configure summary... ERROR: No locking available. Running Samba
would be unsafe
configure: error: summary failure. Aborting config

tob at blackbox ~/samba-2.2.9/source


after hacking/forcing configure to go on by inserting
samba_cv_HAVE_FCNTL_LOCK=yes

the "configure" runs till' end with no further complaints.

moreover: "make" runs through without complaints (some C warnings
which look like expected ..).

then "make install" has it's problems:

$ make install

...

after manually copying the binaries like "make install" tried, I
reran "make install" to get the codepages installed, since now
it can find the binaries needed for this

then, I copied C:\cygwin\home\tob\samba-2.2.9\examples\smb.conf.default
to C:\cygwin\usr\local\samba\lib\smb.conf
with slight editing

now, at least basic functionality seem to work:

tob at blackbox ~
$ smbd -i -d 10 -s /usr/local/samba/lib/smb.conf
...

and

$ smbclient -L localhost

so this leaves me with the question:
Is the fcnlt/locking issue on Cygwin significant?

I just learned there is a VFS interface to implement modules
to do various unusual things. Is this the recommended way of
extending Samba?
