[boost] [1.38.0] beta 2 release candidate

The beta 1 release candidate from earlier in the week had enough issues that I decided not to push it out to sourceforge. Most (all?) of those issues have been corrected, and a new release candidate is up at http://boost.cowic.de/rc/ If no showstoppers surface I plan to move this beta to sourceforge tomorrow (Friday) and announce it here, the users list, and the announce list. The final 1.38.0 release would then come about week later. There are pending bug fixes for Boost.Python and Boost.Asio that are not in the beta but Dave and Chris are planning to have ready for the final release. --Beman
