Algorithm without file-level logic: 0. Remove empty lines 1. Reduce part of translation unit after last line starting with '#' using all available passes. 2. Aggressively eliminate / replace with forward declaration any unused function / classes. 3. Move to the next non-empty section between lines starting with '#' -- Regards, Konstantin
