I don't see why you think there's any problem in C99 terms. The for
statement forms a block (6.8.5#5 first sentence); its body forms a block
whose scope is a strict subset of that of the for statement (second
sentence) and the compound statement is itself a block (whether the same
block or a different one from that of the body as body doesn't matter in
this case, but if the body is a labeled compound statement then you'd have
distinct scopes). As these are distinct blocks, they are distinct scopes;
you can declare i in the block which contains the for statement, and in
the declaration part of the for statement, and in the body of the for
statement.
