It's also the way the bjam invocation is documented in the new Getting
Started guide and Boost.Build v2 documentation

Judging from the diagnostics and the fact that other runners don't
have this problem, I don't think that multiple toolsets have anything
to do with it. It's the "cw-8.3/runtime-link=static" piece that is
causing grief here.

Thank you. What I was trying to say, though, that at the moment the
"cw-8.3/runtime-link=static" toolset specification doesn't work,
'--toolset=' option present or not.

Sorry, I don't see why I should be required to write a file that says

    using msvc : 7.1 ;

instead of simply being able to request the same in the command line.

I don't see how saying

    using msvc : 7.1 ;

would make my registry more organized.
