[Boost-users] MPL map / multi index dependency bug

The following code does not compile using gcc 3.4.3.  I tried it with the 
same results using 1.32 and 1.33.  Reversing the order of the #includes 
fixes the problem.

Is this a known order dependency?  If so, I couldn't find it documented 
anywhere.

#include <boost/multi_index_container.hpp>
#include <boost/mpl/map.hpp>

int main()
{
   return 0;
}

Compiler output:
