The C schema says almost nothing about C.  It lists one kind of comment
and a few type names.  Significantly, it says almost nothing about the
semantics of even the tiny fragment of C presented.

Attempts at a universal compiler stalled in the 1980s (though there may
have been some new developments since I stopped looking) because
expressing the semantics of different languages is so very hard.  In
fact, much of the interest in pursuing the idea came from benefits that
would be derived simply from having a language's semantics formally
described.

I don't think there is anything to see here.  If the author had come up
with some new ways to tackle any of the problems, he would be telling
people about these, not saying "be patient" (and bad-mouthing CPython).
