The layout of the original code is preserved. All changes you apply to
the parse tree are local and don't affect the code outside the scope
of the modified nodes.

However, preprocessing is a separate stage that is delegated
from 'occ' down to an external tool. I don't think comments are currently
preserved when the preprocessor is invoked that way. If you need this
you may want to preprocess the file yourself (using 'gcc -E -C' for
example) and then invoke 'occ' on the result.
But I could be wrong. Grzegorz ?
