1436 (make_binding_level): Use ggc_alloc_cleared or memset.
1437 (lookup_tag): Remove struct binding_level* parameter. All
1438 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1439 current_binding_level->tags if asked for thislevel_only or if
1440 we might have to diagnose "struct foo; union foo;"
1441 (pushlevel): Ignore argument. Do not push another binding
1442 level on the transition from the parameters to the top level
1443 of the function body; just tweak the flags and proceed.
1444 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1445 a function body, separate the parameter list from the
1446 top-level local variables.
1447 (set_block): Do nothing.

1449 shadowed_tags if necessary.

1456 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
1457 (start_function): Don't set subblocks_tag_transparent.
1458 (finish_function): Fix up the binding_level stack for totally
1459 empty functions. Otherwise, don't call poplevel.
1461 * c-common.c (shadow_warning): MANDATORY argument is no longer
1462 necessary. Always use plain warning.
1463 * c-common.h: Update to match.

1466 hit the FUNCTION_DECL.

1491 (c_print_identifier): Update to match changes to struct
1493 (poplevel): Delete #if 0 block. Make externals invisible
1494 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1495 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1496 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1497 (duplicate-decls): For real parm decl after a forward decl,
1498 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1499 foo(...) { } with only a warning. Say whether a previous
1500 declaration was implicit.
1501 (warn_if_shadowing): Now handles all shadowing, not just
1502 local-over-local. Clarify comments.
1503 (pushdecl): Rewritten. There is no longer a distinction
1504 between global and local symbol values; they're all
1505 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1506 DECL_EXTERNAL decls, and use any_external_decl to check
1507 against previous externals. Kill #if 0 blocks. Don't
1508 tolerate error_mark_node being NULL.

1510 Objective C (the only user) needs.
1511 (pushdecl_function_level): New function.
1512 (implicitly_declare): Create ordinary decls with

1528 from build_external_ref.

1533 IDENTIFIER_GLOBAL_VALUE.
