Fast enough that you'd have to have a very large project for incremental 
builds to gain you anything. Maybe you could gain time if the incremental 
builds were done in parallel, but even then, the build time is going to be 
dwarfed by the link time in a lot of programs. Most projects aren't going to 
be big enough to really gain much from incremental builds. I'd only worry 
about that if I were doing a large application and building it was 
demonstratively slow.
