Stefan and Lisandro did most of the work on this front, but much of  
what we did was use a lot of #defines to point things to the right  
places, and write (inline) wrapper functions that wrapped the API  
where things differed.

While it works very well for our target (machine generated C) I don't  
know how applicable it would be to his domain.
