If I start bjam in comand line window then I run into various compilation errors while building boost.1.33.1, RC_1_34_0 cvs and cvs HEAD (1.35.0). If I redirect bjam output to a file with ">" command everything works just fine. Really strange and I don't know why. Hope this helps. [Sorry, skipped] With best regards, Serge Skorokhodov.
