@fribbledom The big problem with this is that you can't compare lines of code across languages. There is also a mix of interpreted and compiled languages listed, so comparing object code sizes is also irrelevant.
One could find one of Capers Jones' books or papers with published average LOC per function point and do a (still flawed, but much more accurate) comparison of function points.

Agreed, I really don't read too much into this, it's just a fun number. Also most of it are actually generated C headers.
