1597 we might have to diagnose "struct foo; union foo;"
1598 (pushlevel): Ignore argument. Do not push another binding
1599 level on the transition from the parameters to the top level
1600 of the function body; just tweak the flags and proceed.

1602 a function body, separate the parameter list from the
1603 top-level local variables.
1604 (set_block): Do nothing.

1648 (c_print_identifier): Update to match changes to struct
1650 (poplevel): Delete #if 0 block. Make externals invisible
1651 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1652 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1653 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1654 (duplicate-decls): For real parm decl after a forward decl,
1655 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1656 foo(...) { } with only a warning. Say whether a previous
1657 declaration was implicit.
1658 (warn_if_shadowing): Now handles all shadowing, not just
1659 local-over-local. Clarify comments.
1660 (pushdecl): Rewritten. There is no longer a distinction
1661 between global and local symbol values; they're all
1662 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1663 DECL_EXTERNAL decls, and use any_external_decl to check
1664 against previous externals. Kill #if 0 blocks. Don't
1665 tolerate error_mark_node being NULL.

1667 Objective C (the only user) needs.
1668 (pushdecl_function_level): New function.
1669 (implicitly_declare): Create ordinary decls with
1670 C_DECL_IMPLICIT set. Recycle old decls, however they got
1672 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
1673 for C_DECL_INVISIBLE symbols.

1682 global_binding_level in extremis.
1684 * c-typeck.c (undeclared_variable): New static function, split
1685 from build_external_ref.

1690 IDENTIFIER_GLOBAL_VALUE.
