 Hello,

 Calling locked() on a recursive mutex on Win32 (haven't tried other
 platforms) always returns true.

 The implementation of this function (pasted below) compares the active
 count against MIN_INT and the result is always true.

 A search for this function in the tests did not yield any results. It does
 not seem like this function is tested.

 From a review of the most recent source from subversion, the bug doesn't
 seem to be fixed.

 Thanks.

 ----------------

  bool locked()
  {
      return get_active_count()>=lock_flag_value;
  }

 BOOST_STATIC_CONSTANT(long,lock_flag_value=0x80000000);
