While / / c / i++ / is not a valid C code, no error is currently triggered on the last */.
I imagine that adding a regex for that token in the 'statements' state is enough for this.
I attach an mercurial export, mostly to learn whether that's the proper way to submit patches (I've used mostly darcs and git, never mercurial...)
