It works! Yay!!

You could have:

    generators.register-c-compiler msvc.compile.idl : IDL : MSTYPELIB H
    C(%_i) : <toolset>msvc ;

...but then you would need some crazy logic to work out the _proxy.c and 
_dlldata.c files...

...unless you can do something cool with the C(%_i) target to get the 
_proxy.c and _dlldata.c names.
