You said above you are hacking that mechanism. Specifically, this line in

        toolset.flags $(toolset).compile CFLAGS $(conditions) : /Zc:forScope /Zc:wchar_t ;

This is the only place where this option is added. If you removed it there, did you
cleaned & rebuilt everything? (Use bjam --clean). You can use "bjam -n" to see
the commands that are executed, and check if that option is still passed or not.
