I just tried it myself, and it still doesn't work.  There are no 
apparent GCC runtime dependencies this time, but the generated C code is 
relying on inline functions which are not supported by MS C.  This could 
be fixed easily enough, but I'm not sure it's worth the effort.  Any 
non-trivial program is going to have dependencies on the GCC runtime.

I'll update the documentation.
