------------------------------------------------+---------------------------
 Commit r57889 on boost/thread/win32/once.hpp has broken the POD guarantees
 of boost::flag_once by adding a destructor and introduced static
 initialization order problems.

 This in turn introduces problems in other part of Boost.Thread that relies
 on boost::flag_once as a static entity such as thread_specific_ptr
 (source:trunk/libs/thread/src/win32/thread.cpp#L28_at_57889), leading to
 segfaults in some applications. For more details, see boost.devel post
 [http://thread.gmane.org/gmane.comp.lib.boost.devel/203959 "[thread]
 thread_specific_ptr and static initialization order"].
