Hi, I have one more comment. I dumpled bjam output to file and I noticed there are some errors in the log. All those errors are related to manifest. Here are lines with errors I cutted from bjam output log file: bin\boost\libs\test\build\boost_prg_exec_monitor.dll\vc-8_0\debug\runtime-link-static\threading-multi\boost_prg_exec_monitor-vc80-mt-sgd-1_34.dll.manifest : general error c1010070: Failed to load and parse the manifest.
