1604 we might have to diagnose "struct foo; union foo;"
1605 (pushlevel): Ignore argument. Do not push another binding
1606 level on the transition from the parameters to the top level
1607 of the function body; just tweak the flags and proceed.

1610 top-level local variables.
1611 (set_block): Do nothing.

1655 (c_print_identifier): Update to match changes to struct
1657 (poplevel): Delete #if 0 block. Make externals invisible
1658 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1659 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1660 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1661 (duplicate-decls): For real parm decl after a forward decl,
1662 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1663 foo(...) { } with only a warning. Say whether a previous
1664 declaration was implicit.
1665 (warn_if_shadowing): Now handles all shadowing, not just
1666 local-over-local. Clarify comments.
1667 (pushdecl): Rewritten. There is no longer a distinction
1668 between global and local symbol values; they're all
1669 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1670 DECL_EXTERNAL decls, and use any_external_decl to check
1671 against previous externals. Kill #if 0 blocks. Don't
1672 tolerate error_mark_node being NULL.

1674 Objective C (the only user) needs.
1675 (pushdecl_function_level): New function.
1676 (implicitly_declare): Create ordinary decls with
1677 C_DECL_IMPLICIT set. Recycle old decls, however they got
1679 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
1680 for C_DECL_INVISIBLE symbols.

1689 global_binding_level in extremis.
1691 * c-typeck.c (undeclared_variable): New static function, split
1692 from build_external_ref.

1697 IDENTIFIER_GLOBAL_VALUE.
