well we had a Java application that ran to 1.5 million lines of code (OK, the definition of a 'line of code' is somewhat flexible, but you get my point), and that would chew up somewhere around 500MB in order to build (this was about 16 months ago; my memory's hazy on the exact amount). luckily only about 30,000 lines of that were hand-written, we built a code generator to do the rest :) cheers Jules
