This would be a big step forward. I've been testing various 
libraries with ImportC in an attempt to identify bugs, 
limitations, and workarounds. I've gotten a lot of mileage from 
Iain's file, in the sense that it was sufficient to get most of 
those files to compile.

What it can't solve is duplicate function definitions across 
preprocessed files. That's where a compiler solution would be 
valuable. I assume their solution will address this.
