The different services in Samba 4 can be loaded from DSO's. You should
simply be able to build the wins part as a separate .so that can be
packaged separately. Samba will automatically enable the WINS support if
the DSO is available. 

I'd rather not have different binaries as that would require us to do
communication between the various different binaries and it makes it
harder to manage a running samba daemon (starting/stopping,
starting/killing Samba as part of the test suite, etc).

What do you think of using DSO's for this?

Cheers,

Jelmer
