1462 (make_binding_level): Use ggc_alloc_cleared or memset.
1463 (lookup_tag): Remove struct binding_level* parameter. All
1464 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1465 current_binding_level->tags if asked for thislevel_only or if
1466 we might have to diagnose "struct foo; union foo;"
1467 (pushlevel): Ignore argument. Do not push another binding
1468 level on the transition from the parameters to the top level
1469 of the function body; just tweak the flags and proceed.
1470 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1471 a function body, separate the parameter list from the
1472 top-level local variables.
1473 (set_block): Do nothing.

1475 shadowed_tags if necessary.

1482 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
1483 (start_function): Don't set subblocks_tag_transparent.
1484 (finish_function): Fix up the binding_level stack for totally
1485 empty functions. Otherwise, don't call poplevel.
1487 * c-common.c (shadow_warning): MANDATORY argument is no longer
1488 necessary. Always use plain warning.
1489 * c-common.h: Update to match.

1492 hit the FUNCTION_DECL.

1517 (c_print_identifier): Update to match changes to struct
1519 (poplevel): Delete #if 0 block. Make externals invisible
1520 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1521 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1522 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1523 (duplicate-decls): For real parm decl after a forward decl,
1524 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1525 foo(...) { } with only a warning. Say whether a previous
1526 declaration was implicit.
1527 (warn_if_shadowing): Now handles all shadowing, not just
1528 local-over-local. Clarify comments.
1529 (pushdecl): Rewritten. There is no longer a distinction
1530 between global and local symbol values; they're all
1531 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1532 DECL_EXTERNAL decls, and use any_external_decl to check
1533 against previous externals. Kill #if 0 blocks. Don't
1534 tolerate error_mark_node being NULL.

1536 Objective C (the only user) needs.
1537 (pushdecl_function_level): New function.
1538 (implicitly_declare): Create ordinary decls with
1539 C_DECL_IMPLICIT set. Recycle old decls, however they got

1551 global_binding_level in extremis.
1553 * c-typeck.c (undeclared_variable): New static function, split
1554 from build_external_ref.
1555 (build_external_ref): Use DECL_CONTEXT, not
1556 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
1557 an instance variable. Restructure for clarity.

1559 IDENTIFIER_GLOBAL_VALUE.
