[boost] [serialization] 100% pass in latest Mandrake test

Robert - Things are looking good in my latest round of regression tests, all tests pass, down to a few warnings. Nice work! http://boost.sourceforge.net/regression-logs/cs-LinuxMandrake.html I even included the date_time serialization tests (exercises the code that serializes dates, times, durations, etc) in this run :-) Jeff
