I am using XLC under Linux/PPC with boost 1.33.1 compiled with XLC 8.0. I get the following errors when I attempt to compile the demo_xml.cpp example to compile. xlc++ -o demo_xml-xlc demo_xml.cpp -qstaticlink -I/home/jdavidso/boost/boost_xlc/include/boost-1_33_1 -L/home/jdavidso/boost/boost_xlc/lib -lboost_serialization-xlc-mt -lpthread "/home/jdavidso/boost/boost_xlc/include/boost-1_33_1/boost/archive/detail/oserializer.hpp", line 333.13: 1540-1109 (S) The use of undefined class "boost::STATIC_ASSERTION_FAILURE<0>" is not valid.
