Hello,
I'm currently packaging dovecot 2.0.3 under Mandriva Linux. It has been using LDFLAGS="-Wl,--as-needed -Wl,--no-undefined" for shared libraries for over two years1. And I've found there are lots of linking problems with dovecot 2.0.3.
After some investigation, I've made small patch regarding dovecot 2.0.3, posted here: http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/dovecot/branches/...
Even after applying mentioned patch, it still produce following errors:

Could somebody take a look?
Thanks.
