I'm quite sure, actually (though I only took a quick glance at them)! :-)

(It'll be interesting to see if gpc's adopting other features can keep pace
with new Pascal dialects being developed... ;-)

That's what I meant with my "bug report". I didn't check if the type or the
var declaration caused the internal error.

I just found another bug -- or is it an instance of the "cannot write
longint variables" known bug?

var c:cardinal value $ffffffff;
begin
 writeln(c)
end.

...writes -1.
