[boost] multi-index warnings

All,

I'm attempting to upgrade to boost_1_34_0 from boost_1_33_1 and I get
the following warnings from a hashed_unique index. The same code
compiles clean on boost_1_33_1 with gcc-4.1.1 and gcc-4.1.2.

Am I doing something wrong or this is a deficiency introduced in 1_34_0?

Thanks,
Marius

Sample code:

           boost::multi_index::hashed_unique
         <
            boost::multi_index::tag<server>,
            boost::multi_index::const_mem_fun
            <
               SessionLink,
               int,
               &SessionLink::serverFD
            >
	   >
