[boost] [1.35.0] Test regressions

For a full list of 1.35.0 test regressions, see http://beta.boost.org/development/tests/release/developer/summary.html There are a few 1.35.0 regressions I'm not particularly concerned about; VC++ 7.1 is now old news, and no one seems to care much about the Intel/Windows compiler. Given that VC++ 9.0 has been out for awhile now, it would be nice to kill off a few more of those regressions before 1.35.0 ships: * Conversion * Graph * Python * TR1 Red regressions I'm concerned about are: * Numeric/interval on Darwin. * Serialization on Darwin. * Spirit on Darwin. If anyone can quickly come up with fixes, there is still (barely) enough time to get them into 1.35.0. --Beman
