Personally, I'd rather we take a few days to fix this, rather than ship "as 
is".

Vladimir: if there's anything I can do to aid testing of any changes then 
let me know.

I believe that if we have "using msvc ;" in user-config.jam then it 
automatically detects the available versions and sets the most recent as the 
default?  Can we rig it so that --toolset=msvc has the same effect?

The only issue is what happens if the user invokes bjam from within an msvc 
command prompt.  Should we expect --toolset=msvc to invoke the compiler 
that's currently in the path and detect it's version correctly?  My gut 
feeling is this may be too much to ask for, but if so we should say so in 
the docs (Dave?).
