In principle, it should be OK. Could you send a concrete example of C
conde on which it does not work? It is possible that there is some
problem in parsing baz, and it is just skipping over it. For this, you
can run spatch --parse-c on your file. If there is a BAD or bad in front
of the code that you expect to have changed, then there may be a problem.
