Why? Assuming you want C code at the end and you're going to feed it to
a compiler, what does this accomplish besides cleaning up the code a
little? And how often do you really see code like this? If it's
frequent, you might consider training your programmers to write better
code, rather than wasting time on a tool to clean it up afterwards.
