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 years[1]. 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/dovecot2/current/SOURCES/dovecot-2.0.3-linkage.patch
Even after applying mentioned patch, it still produce following errors:

Could somebody take a look?
Thanks.
