9496 (make_binding_level): Use ggc_alloc_cleared or memset.
9497 (lookup_tag): Remove struct binding_level* parameter. All
9498 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
9499 current_binding_level->tags if asked for thislevel_only or if
9500 we might have to diagnose "struct foo; union foo;"
9501 (pushlevel): Ignore argument. Do not push another binding
9502 level on the transition from the parameters to the top level
9503 of the function body; just tweak the flags and proceed.
9504 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
9505 a function body, separate the parameter list from the
9506 top-level local variables.
9507 (set_block): Do nothing.

9509 shadowed_tags if necessary.

9519 empty functions. Otherwise, don't call poplevel.
9521 * c-common.c (shadow_warning): MANDATORY argument is no longer
9522 necessary. Always use plain warning.
9523 * c-common.h: Update to match.

9551 (c_print_identifier): Update to match changes to struct
9553 (poplevel): Delete #if 0 block. Make externals invisible
9554 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9555 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9556 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9557 (duplicate-decls): For real parm decl after a forward decl,
9558 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9559 foo(...) { } with only a warning. Say whether a previous
9560 declaration was implicit.
9561 (warn_if_shadowing): Now handles all shadowing, not just
9562 local-over-local. Clarify comments.
9563 (pushdecl): Rewritten. There is no longer a distinction
9564 between global and local symbol values; they're all
9565 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9566 DECL_EXTERNAL decls, and use any_external_decl to check
9567 against previous externals. Kill #if 0 blocks. Don't
9568 tolerate error_mark_node being NULL.

9570 Objective C (the only user) needs.
9571 (pushdecl_function_level): New function.
9572 (implicitly_declare): Create ordinary decls with

9588 from build_external_ref.
