I believe Oberon uses a library as well. C's just file-based because its modularity support is so weak and low-level that it has no choice. I'd think the best way for you to get a handle on this would be to go download the evaluation version of ObjectAda and play with it a while. (Go to http://www.aonix.com and click on "Downloads" on the sidebar.) It uses Tucker's Favorite Front End, which is both widely used by non-Gnat compilers, and fairly representative of a typical approach. -- T.E.D.
