If they are of help to you, then that's great.  It is not always easy to 
know what will be useful.

I think if we can understand what you are trying to do, and why, it will 
be easier to help.  (I say "we" - maybe I'm the only one that doesn't 
understand.  But hopefully I'm not the only one that is happy to give 
comments that might be useful!)

Are you trying to make your own C compiler here, divided into two parts? 
  If so, why?  What's the motivation - what will make this compiler 
different from others?  As an IL, this limited C would be very poor in 
terms of good code generation, static error checking, or debugging.  It 
could be fairly portable, but I think would lose the platform or 
compiler specific features that are often useful for real programs and 
libraries.

(Of course, fun, learning and your own interest is always perfectly good 
motivation as far as I am concerned.)
