I doesn't necessarily have to look like `$$=...'. Parsing the C code
is probably a bit too much to expect from bison.

It might be nice if it's possible to arrange things so it will
trigger some kind of "undefined" value from the compiler, but I
guess that'll at least require some hacking of the skeleton files.
(I don't know the details, but you can try it for yourself, and
report if you have success.)
