GNUstep LoginPanel: failed to build with GNU runtime

Hello,

I recently fetched LoginPanel from svn gap repo.
I installed: libpam0g-dev.
I tried to buid the app with this arg:
> have-pam=yes

This error happened:
> Authenticator.m:210:11: error: invalid use of undefined type struct 
> passwd

Could you explain what is missing or what I made wrong?

- OS: Debian Trixie
- GNUstep system up to date
- Runtime: GNU

Regards,
Patrick
