[Dovecot] Dovecot 1.1 rc9 compilation warnings

[Chris Wakelin]

I've tried compiling 1.1.rc9 on everything to hand and I get various 
compilation warnings (but the compilation finishes). I don't know 
whether any of them are worth tracking down?

I'm guessing most of the differences depend on the default gcc options 
and a couple of them are probably specific to our setup.

All were configured with

./configure --prefix=/opt/RDGdovect --with-ssl=openssl --with-ldap

Best Wishes,
Chris
