Ough, year... I will use it in commercial compiler... Sure... Guys... Did you 
read my mail?
There is an existing static analisys tool called Wasp. It is written by my 
science advisor Vladimir Shelekhov. (http://www.iis.nsk.su/wasp/)
It targets Java, Module-2 and Oberon-2.
I personally prefer C++. That is why I like to use gcc frontend information.
I plans to write static analisys tool for C++. Will it be commercial, or 
not... I do not know yet. For me it is an interesting science problem for my 
doctor paper.
