	* c-tree.h (grokfield): Add a "tree *" argument.
	* c-decl.c (grokdeclarator): Take a pointer to the decl's attributes.
	Chain nested decl attributes to it.  Don't call decl_attributes here.
	(groktypename): Pass grokdeclarator a pointer to the attribute list.
	(start_decl, grokparm, push_parm_decl, start_function): Likewise.
	(grokfield): Take a pointer to the decl's attributes and pass
	it to grokdeclarator.
	* c-parser.c (c_parser_struct_declaration): Update the calls to
	grokfield.  Call decl_attributes for anonymous struct and union
	fields.
