[M3devel] Latest parse.c

See this snip from gcc/gcc/config/winnt.c:

>   formal_type = TYPE_ARG_TYPES (TREE_TYPE (decl));
>   if (formal_type != NULL_TREE)
>     {
>       /* These attributes are ignored for variadic functions in

>         return DECL_ASSEMBLER_NAME (decl);

We need a void_type_node there -- void_list_node now captures that  
properly.

I wonder if the remaining problem with the wrong @N value is because  
we don't have a complete type on the formals?
