[boost] [serialization]

Hi, I have a few blocking compilation/link problems on the develop branch for which to fixes are pending (46 (3 lines) & 45(1 line)). 45 is a bug in the code I thin, 46 probably works just fine on most platform, but not on mine (recent Intel compiler on CentOS 6.5, which mean advanced features, but old headers). Boths are breaking are breaking some tests on Boost.MPI. Could someone have a look at it ? Regards Alain
