Is it possible to write a short example how a it could be referred the
tree of variable field? Let's say that we have somewhere defined the
following source code:

--- code ---
typedef struct MyType
{
 int field1;
 int field2;
}

MyType *var;
--- code ---

What I want is to get the tree node of "var->field1". For now I can
get the tree of the "var" declaration with the code bellow.

tree var_decl = lookup_name(get_identifier("var"));

And I suppose that, having "var_decl" I can get a tree to the "field1"
field of "var". Is there any function e.g. lookup_decl_field that does
it?
