That's because you define a variable after what is effectively a
statement on the first line. All variable declaration have to come
at the start of a block, so when you have int i;;  you have;

	int i;
	/* empty statment */ ;
	char *s;

But you can't define a variable after a statement. In the below
examples ...

it makes no difference, because statements can always come after
statements :) It's just an inconsistency in that one compiler
considers ;; just ignorable, and the other (more properly imo)
considers it an empty statement.
