1441 (make_binding_level): Use ggc_alloc_cleared or memset.
1442 (lookup_tag): Remove struct binding_level* parameter. All
1443 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1444 current_binding_level->tags if asked for thislevel_only or if
1445 we might have to diagnose "struct foo; union foo;"
1446 (pushlevel): Ignore argument. Do not push another binding
1447 level on the transition from the parameters to the top level
1448 of the function body; just tweak the flags and proceed.
1449 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1450 a function body, separate the parameter list from the
1451 top-level local variables.
1452 (set_block): Do nothing.

1454 shadowed_tags if necessary.

1461 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
1462 (start_function): Don't set subblocks_tag_transparent.
1463 (finish_function): Fix up the binding_level stack for totally
1464 empty functions. Otherwise, don't call poplevel.
1466 * c-common.c (shadow_warning): MANDATORY argument is no longer
1467 necessary. Always use plain warning.
1468 * c-common.h: Update to match.

1496 (c_print_identifier): Update to match changes to struct
1498 (poplevel): Delete #if 0 block. Make externals invisible
1499 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1500 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1501 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1502 (duplicate-decls): For real parm decl after a forward decl,
1503 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1504 foo(...) { } with only a warning. Say whether a previous
1505 declaration was implicit.
1506 (warn_if_shadowing): Now handles all shadowing, not just
1507 local-over-local. Clarify comments.
1508 (pushdecl): Rewritten. There is no longer a distinction
1509 between global and local symbol values; they're all
1510 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1511 DECL_EXTERNAL decls, and use any_external_decl to check
1512 against previous externals. Kill #if 0 blocks. Don't
1513 tolerate error_mark_node being NULL.

1515 Objective C (the only user) needs.
1516 (pushdecl_function_level): New function.
1517 (implicitly_declare): Create ordinary decls with

1533 from build_external_ref.

1538 IDENTIFIER_GLOBAL_VALUE.
