* c-ada-spec.c (dump_ada_import): Use boolean and fix formatting.
	(is_char_array): Fix formatting.
	(dump_template_types): Likewise.
	(dump_generic_ada_node): Rename into...
	(dump_ada_node): ...this.
	<POINTER_TYPE>: Remove superfluous space.  Use generic address for
	incomplete structures and not for empty structures.  Do not use it
	when forward declarations are needed.
	(dump_forward_type): New function.
	(dump_nested_types): Remove FORWARD parameter.  Do not consider
	TREE_VISITED and do not generate a forward declaration.  Only dump
	original nested types for nested declaration.
	(dump_nested_type) <POINTER_TYPE>: Call dump_forward_type.
	<ARRAY_TYPE>: Likewise if the component type is an anonymous pointer.
	<RECORD_TYPE>: Do not consider TREE_VISITED.
	(dump_ada_declaration): Use booleans and fix formatting throughout.
	<TYPE_DECL>: Skip incomplete structures and not empty structures.
	Call dump_forward_type instead of dump_nested_types for a typedef.
	Remove superfluous check and adjust call to dump_nested_types.
	<POINTER_TYPE>: Call dump_forward_type and fall through.
	(dump_ada_struct_decl): Rename into...
	(dump_ada_structure): ...this.  Do not special-case empty structures.
