The practical problem I have is that parsing C does
require *client* state to be passed around.

So the internal reentrancy of ocamlyacc parsers isn't
enough. The client has to wrap all the parses with
copyup/copy down code too... and they didn't.

If there been a state variable the authors might
have taken the trouble to use it.

Ocamllex lexers are now very easy to make reentrant!
