1496 current_binding_level->tags if asked for thislevel_only or if
1497 we might have to diagnose "struct foo; union foo;"
1498 (pushlevel): Ignore argument. Do not push another binding
1499 level on the transition from the parameters to the top level
1500 of the function body; just tweak the flags and proceed.

1502 a function body, separate the parameter list from the
1503 top-level local variables.

1516 empty functions. Otherwise, don't call poplevel.

1548 (c_print_identifier): Update to match changes to struct
1549 lang_identifier.
1550 (poplevel): Delete #if 0 block. Make externals invisible
1551 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1552 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1553 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1554 (duplicate-decls): For real parm decl after a forward decl,
1555 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

1558 (warn_if_shadowing): Now handles all shadowing, not just
1559 local-over-local. Clarify comments.
1560 (pushdecl): Rewritten. There is no longer a distinction
1561 between global and local symbol values; they're all
1562 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1563 DECL_EXTERNAL decls, and use any_external_decl to check
1564 against previous externals. Kill #if 0 blocks. Don't
1565 tolerate error_mark_node being NULL.
1566 (pushdecl_top_level): Handle only those cases which
1567 Objective C (the only user) needs.
1568 (pushdecl_function_level): New function.
1569 (implicitly_declare): Create ordinary decls with
1570 C_DECL_IMPLICIT set. Recycle old decls, however they got
1571 created.
1572 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
1573 for C_DECL_INVISIBLE symbols.

1582 global_binding_level in extremis.
1584 * c-typeck.c (undeclared_variable): New static function, split
1585 from build_external_ref.
1586 (build_external_ref): Use DECL_CONTEXT, not
1587 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
