 From what Iain has said that I remember, you can only use the last 3 
major versions in binary form to compile the next version. They are 
pretty strict.

That is all I know on the subject.

We already have it for generating headers.

```
   -HCd=<directory>  write C++ 'header' file to directory
   -HCf=<filename>   write C++ 'header' file to filename
```

It is incomplete, but there is enough there to see that it is in fact 
possible to do what I am suggesting and has quite desirable use cases 
outside of compilers.

This isn't a far fetched idea. It already exists.
