[antlr-interest] Question about example Ansi C grammar for antlr v3

[Fredrik Ohrstrom]

Sadly enough ;-) , the following c-code compiles both using gcc and cl.exe

---------------
typedef int alfa;
typedef int beta;

struct { struct { int z; } alfa; } c;

int main(int alfa)
{
   beta beta;
}
---------------

The example antlv3 c-parser found on the antlr homepage will wrongly
parse the alfa inside the struct as a type_id and not a direct_declarator.
In the same way it wrongly parses the argument alfa and the function local beta.

I have tried to extend the grammar to fix this, unfortunately I have not
been able to solve all the cases in the example, only the arg and
local var case.

What is the correct way of solving this?
