I have attached a simple patch to the file boost/tools/build/v1/vc-8_0-amd64-tools.jam that accounts for an apparent name change to a .bat file in the Visual Studio 2005 Beta 2 install tree. I say "apparent name change" because I am assuming that the .jam file was made with Visual Studio 2005 Beta 1, with which I have no experience. If I am doing something wrong in trying to build Boost to target the AMD64 architecture on Windows which would make this patch useless, please let me know. -Patrick -- Patrick L.
