There is bug in the Qt4 moc tool, that makes it incompatible with some Boost 
files from Boost-1.48.

In CGAL-4.0-beta1, we have introduced a workaround. Copy the following lines 
near the beginning of CGAL-3.9/include/CGAL/config.h, if you want to fix that 
bug keeping CGAL-3.9:


// Workaround to the following bug:
//   https://bugreports.qt.nokia.com/browse/QTBUG-22829
#ifdef Q_MOC_RUN
// When Qt moc runs on CGAL files, do not process
// <boost/type_traits/has_operator.hpp>
#  define BOOST_TT_HAS_OPERATOR_HPP_INCLUDED
#endif


I am not really proud of that workaround of mines, but at least it works.
