winbind build/link question

[Roylance, Stephen D.]

I'm trying to use some of the functions in winbind_nss.c in my winbind_aix.c
module.  It compiles, but when I try to link it fill_pwent is unresolved.
What do I need to link against in order to get fill_pwent and such from
winbind_nss.c?  I tried making nsswitch/winbind_nss.o and linking against
that, but it still didn't resolve fill_pwent.

I realize this is basic stuff that maybe I should be able to figure out from
the Makefile, but it's an order of magnitude more complex than anything I've
tried to work with before.  

Bear with me, I'm trying,
