[antlr-interest] C++-Target - write AST as XML

Hi Jimi,

I want some form of the input file in a XML representation. If its a
generic AST or something else, doesn't matter, its going to be
transformed by XSLT anyway.

My current problem is to get the AST generation running with the
Cpp-Target: On setting "output=AST;", a ton of error messages is
generated at compiletime. These error messages look like this:

error: TreeType doesn't name a type.
error: ‘struct myParser_timeStamp_return’ has no member named ‘tree’
(a follow up of #1)
error: ‘ADAPTOR’ was not declared in this scope
error: ‘INPUT’ was not declared in this scope
error: ‘EXCEPTION’ was not declared in this scope

Obviously, something is not included or a type not defined - any idea
how to solve this?
