I bail out, maybe I will look at it tomorrow.  I hoped it wouldn't be this
complicated (im tired). I will follow the other approach and substitution 
all occurencies of $& and $1-$9 instead.

BTW: Is there a reason that functions not found in Ruby's .H files, often
has a 'static' tag, so thats impossible to extern them?

Would it make any sense to remove all 'static' tags?
