Hi Matthew
I have actually tried this earlier, but it does not work as expected,
probably because of greedy matching. I have produced the list of
warning differences before and after over the files, when using this

I think this will match against:
$prototype =~ m/^($type1)\s+($name)\s*$prototype_end/
