Comment (by viboes):

 Boost 1.50 avoids these warnings if you define
 BOOST_THREAD_PROVIDES_GENERIC_SHARED_MUTEX_ON_WIN or
 BOOST_THREAD_VERSION=3.

 The default value for BOOST_THREAD_VERSION is 2 on 1.50, but will be 3 in
 a near release, so maybe you can already switch.

 I will not try to fix these warning in the legacy code. Let me know if we
 can close this tickets as wontfix.
