By design, it's not a fully compliant ANSI C compiler, so it's never going to be complete, but it's complete enough to, for example, successfully compile Plan 9's driver for the Raspberry Pi USB controller with a minimal porting effort.

So, Dusk's compiler is not apple-to-apple comparable to the other, but comparable enough to give a ballpark idea that its code density compares very, very favorably.

It can be hard to tell how much extra complexity would be introduced by unimplemented features.

Indeed, and it might be why the author didn't try, but I still find it odd to not at least mention how small this C compiler is, even if it is to say that it's not apples-to-apples comparable. I mean, 8x smaller than the smallest C compiler listed is still something notable...

		It certainly sounds like a perfectly usable C dialect.
