Shadow passwds breaks programs with pw_stayopen?

[Marc Lesure]

I just install the shadow password code from Berkeley on one of our
Vax 780's running 4.3-tahoe.  When I did, the programs quot, finger,
find, and others broke.  The programs would core dump and re-compiling
them determined that the common fault was an unresolved reference 
to pw_stayopen.  Looking at the sources on both a 4.3-tahoe with and
without the shadow passwords, I've been unable to find pw_stayopen on 
either.  My questions are where is pw_stayopen defined?  And, Why
did shadow passwords eliminate it?
