[boost] [foreach] [Revision 1.27] tiny problem under eVC4 (and maybe VC6)

Hi, Under eVC++4, foreach_detail_::is_array/is_const causes name conflict with boost::is_array/is_const. (I don't know why.) I hear VC++6 has the same compiler as eVC++4. I renamed them to 'is_array_' and 'is_const_', then it works fine. Regards, MB p-stade.sourceforge.net
