I've looked at this FAQ entry but I don't understand the code snippets.
More specifically, how I am supposed to apply this to my own code. My
problem is that once I see a preprocessor directive I have to look if
there are any other tokens between the directive and the newline before
it besides a whitespace token. Can anyone supply me with a more helpful
example?

Thanks in advance,
