I seem to recall that it had a very smart recompilation algorithm that could drastically reduce the set of files that had to be recompiled after a change had been made. Instead of just using file timestamp and "with" clause dependencies, it would actually look into the code and deduce that most of the recompilations were unnecessary. Very fast - great for big projects. Is this algorithm still patented ?. Are we ever likely to see it in Gnat / gcc ?
