[antlr-interest] adding child node in rewring rule

[Юрушкин Михаил]

I know about this project. But it (OFP project) doesn't fit to my  
requirements
1) it's written in java (I need C target)
2) It doesn't create AST. It's important because, in the past I didn't use  
AST
and had many memory leakages. For Java there're no such problem, but it is  
for C target.
3) They have many fixes (coded in java).
