Sounds great. I suggest adding this to projects/beginner.html
(on second thought maybe not ;-) or start a projects/ada.html?
It is *far* from a beginner's project. Indeed, the main reason it hasn't
been done is that it is a very *hard* project. If you really want to use
ANSI C, you have to figure out how to deal with nested functions. If you
use GNU C, that isn't a problem, but you still have to deal with things
like discriminated records and unconstrained arrays.
