     Type:  Bugs              |      Status:  new    
Milestone:  To Be Determined  |   Component:  None   
  Version:  Boost 1.34.1      |    Severity:  Problem
 Keywords:                    |  
------------------------------+---------------------------------------------
 boost/detail/flyweight_mutex.hpp implements a mutex class based on a
 Win32 CRITICAL_SECTION or using Pthreads according to the
 following pp logic:

 {{{
 #if defined(WIN32) || defined(_WIN32) || defined(__WIN32__)
   // based on CRITICAL_SECTION
 #elif defined(BOOST_HAS_PTHREADS)
   // based on Pthreads
 }}}

 which violates ODR on those environments, such as Cygwin,
 where WIN32 or similar is not a predefined macro but depends
 on the inclusion of <windows.h>.
