OMG! That option is really something! It makes my script useless... I wish I could ++ more than one time.

Regarding regexp: I suspected it too, I tried to //o, but the time was the same. Then I tried to change it to /#define\s+(\w+)(.)(.)/ but the results were still the same. Don't really know why is that. Maybe some buffering of input data? No idea.
