1445 (make_binding_level): Use ggc_alloc_cleared or memset.
1446 (lookup_tag): Remove struct binding_level* parameter. All
1447 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1448 current_binding_level->tags if asked for thislevel_only or if
1449 we might have to diagnose "struct foo; union foo;"
1450 (pushlevel): Ignore argument. Do not push another binding
1451 level on the transition from the parameters to the top level
1452 of the function body; just tweak the flags and proceed.
1453 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1454 a function body, separate the parameter list from the
1455 top-level local variables.
1456 (set_block): Do nothing.

1458 shadowed_tags if necessary.

1465 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
1466 (start_function): Don't set subblocks_tag_transparent.

1468 empty functions. Otherwise, don't call poplevel.
1470 * c-common.c (shadow_warning): MANDATORY argument is no longer
1471 necessary. Always use plain warning.
1472 * c-common.h: Update to match.

1500 (c_print_identifier): Update to match changes to struct
1502 (poplevel): Delete #if 0 block. Make externals invisible
1503 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1504 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1505 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1506 (duplicate-decls): For real parm decl after a forward decl,
1507 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1508 foo(...) { } with only a warning. Say whether a previous
1509 declaration was implicit.
1510 (warn_if_shadowing): Now handles all shadowing, not just
1511 local-over-local. Clarify comments.
1512 (pushdecl): Rewritten. There is no longer a distinction
1513 between global and local symbol values; they're all
1514 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1515 DECL_EXTERNAL decls, and use any_external_decl to check
1516 against previous externals. Kill #if 0 blocks. Don't
1517 tolerate error_mark_node being NULL.

1519 Objective C (the only user) needs.
1520 (pushdecl_function_level): New function.
1521 (implicitly_declare): Create ordinary decls with

1537 from build_external_ref.

1542 IDENTIFIER_GLOBAL_VALUE.
