label_statement ambiguity in parse.h

[Yoann Padioleau <padator@wanadoo.fr>]

In parse.h 'struct statement' the same fieldname
"label_statement" is used multiple times. Is it intended ? 


struct statement {
	enum statement_type type;
	struct position pos;
	union {
		struct /* declaration */ {
			struct symbol_list *declaration;
		};
		struct /* label_arg */ {
			struct symbol *label;
==> HERE		struct statement *label_statement;
		};
                ...
		struct /* labeled_struct */ {
			struct symbol *label_identifier;
==> HERE		struct statement *label_statement;
		};




I guess from the gcc point of view it does not make a difference
as it will point to the same address because in both 
cases the items before have the same type and so size, but
if one day someone change one type, the user may have
some surprise ?
