This seems straightforward:

typedef uint;

- uint
+ unsigned int
Perhaps you were missing the typedef.

This should be the same.

At the moment, that's not possible. I don't think the C parser will
parse the code, and I'm sure that the SmPL parser won't parse the semantic
patch that you would need. But I think it would be easy to add. I can
try to do that when I finish with Nic's if problems.
