[boost] compile boost 1.34.1 x64 within WindowsXP 64

Hi there I try to compile the boost-libs within WinXP 64 but without any success. There aren't any precompiled libraries as for x32? Bjam doesn't have this option, too. So is there anywhere a manual how to compile the 1.3..x boost libraries within WinXP and MSVC8? We use the cl- and sometimes the ippc9.1-compiler. Best, SirAnn
