Milestone:  To Be Determined      |   Component:  thread  
  Version:  Boost 1.49.0          |    Severity:  Problem 
 Keywords:  thread mutex warning  |  
----------------------------------+-----------------------------------------
 I'm using the Boost.Thread library since 1.47.
 When including <boost/thread/thread.hpp> my compiler (mingw 4.6) always
 writes a number of annoying warnings like this:

 ../boost/thread/win32/shared_mutex.hpp:50:99: warning: dereferencing type-
 punned pointer will break strict-aliasing rules [-Wstrict-aliasing]

 another warning is: /boost/thread/win32/shared_mutex.hpp:95:33: warning:
 missing initializer for member
 'boost::shared_mutex::state_data::shared_waiting' [-Wmissing-field-
 initializers]

 Same warnings in 1.47, 1.48 and 1.49 using the same compiler.

 The gcc options used: -pedantic -ansi -std=gnu++0x -Wextra -fpermissive
