c-tree.h (struct language_function): Add arg_info element.
* c-tree.h (struct language_function): Add arg_info element.
* c-decl.c (current_function_arg_info): New.
(grokdeclarator, store_parm_decls): Use it instead of
DECL_ARGUMENTS.
(c_push_function_context, c_pop_function_context): Save and
restore it.
