foreach.hpp:6:17: error: 'boost::BOOST_FOREACH' has not been declared
and foreach.hpp is:
#ifndef FOREACH_HPP
#define FOREACH_HPP

#include <boost/foreach.hpp>

#define foreach BOOST_FOREACH

#endif


Version-Release number of selected component (if applicable):
Boost-1.48.0-1

How reproducible:
Always

Steps to Reproduce:
Compile Wesnoth on Fedora Rawhide
  
Actual results:
See above.

Expected results:
No compilation error.
