Good news is that next version - currenlty checked into the main cvs trunk - resolves the issue in much better manner.
I downloaded the latest main cvs trunk Boost. Bjam generation of the libs are ok. But most if not all tests runned with runtest.bat are failing as "boost::exit_success" is not defined (extract from bjam log follows) ..\..\..\libs\serialization\test\test_polymorphic.cpp(54) : error C2039: 'exit_success' n'est pas membre de 'boost' ..\..\..\libs\serialization\test\test_polymorphic.cpp(54) : error C2065: 'exit_success' identificateur non d,clar, "cl" /Zm800 -nologo EHsc -c -DBOOST_ARCHIVE_TEST=polymorphic_text_archive.hpp -DBOOST_LIB_DIAGN OSTIC=1 /Z7 /Od /Ob0 /EHsc /GR /MDd /Op /Zc:forScope Zc:wchar_t -I"c:\boost\bin\boost\libs\serialization\test" -I"C:\boost" -I" D:\Program Files\Microsoft Visual Studio .NET 003\VC7\include" -I"C:\boost" -Fo"c:\boost\bin\boost\libs\serialization\t est\test_polymorphic_text_archive.test\vc-7_1\debug\threading-multi\test_pol ymorphic.obj" -Tp"..\..\..\libs\serialization\test\test_polymorphic.cpp" It seems that the include <boost/cstdlib.hpp> is missing somewhere??
