     Type:  Bugs          |      Status:  new    
Milestone:  Boost 1.39.0  |   Component:  None   
  Version:  Boost 1.37.0  |    Severity:  Problem
 Keywords:                |  
--------------------------+-------------------------------------------------
 Using boost multi_index in a project that doesn't supply -fexceptions (or
 rather that supplies -fno-exceptions) to the compiler fails at linking
 time because there's an undefined reference to
 boost::throw_exception(std::exception). This appears to be caused by the
 #ifdef stuff in serialization/throw_exception.hpp, which uses
 std::exception if BOOST_NO_EXCEPTIONS is defined. However this define is
 set when exception support is turned off.

 Hence instead of "#ifdef BOOST_NO_EXCEPTIONS" this should probably be
 "#ifndef BOOST_NO_EXCEPTIONS". Changing the header file accordingly makes
 the project I have here link properly.

 First version that breaks is 1.37, in 1.36 the problem doesn't appear.
