12700 current_binding_level->tags if asked for thislevel_only or if
12701 we might have to diagnose "struct foo; union foo;"
12702 (pushlevel): Ignore argument. Do not push another binding
12703 level on the transition from the parameters to the top level
12704 of the function body; just tweak the flags and proceed.

12707 top-level local variables.

12751 (clone_underlying type): Split out of pushdecl.
12752 (c_print_identifier): Update to match changes to struct
12754 (poplevel): Delete #if 0 block. Make externals invisible
12755 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
12756 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
12757 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12758 (duplicate-decls): For real parm decl after a forward decl,
12759 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
12760 foo(...) { } with only a warning. Say whether a previous

12762 (warn_if_shadowing): Now handles all shadowing, not just
12763 local-over-local. Clarify comments.
12764 (pushdecl): Rewritten. There is no longer a distinction
12765 between global and local symbol values; they're all
12766 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
12767 DECL_EXTERNAL decls, and use any_external_decl to check
12768 against previous externals. Kill #if 0 blocks. Don't
12769 tolerate error_mark_node being NULL.
12770 (pushdecl_top_level): Handle only those cases which
12771 Objective C (the only user) needs.
12772 (pushdecl_function_level): New function.
12773 (implicitly_declare): Create ordinary decls with
