[antlr-interest] [C-target] Child-parent relationship

[Jim Idle]

Take a look at antlr.markmail.org for other examples but where are you
trying to get the parent, in the parser before you have built the AST (it
sounds like this) or in the tree walker? You should not need to change any
of the runtime functions; you are probably just making them do things that
are going to get done anyway at the end of the rule. Look at the generated
code for ways to traverse the tree. I suppose there could be a bug, but ut
seems a bit unlikely at this point.
