[boost] compilation warning on HEAD

Subject: [boost] compilation warning on HEAD
From: Gaetano Mendola (mendola_at_[hidden])

The HEAD in trunk have some compilation warnings using gcc 4.7.2
the following will fix some of those.

Another warning about unused result is in here:

libs/serialization/src/basic_iarchive.cpp line 576, the value is
used in a BOOST_ASSERT, I don't know how you manage those cases.

Regards
Gaetano Mendola
