12683 current_binding_level->tags if asked for thislevel_only or if
12684 we might have to diagnose "struct foo; union foo;"
12685 (pushlevel): Ignore argument. Do not push another binding
12686 level on the transition from the parameters to the top level
12687 of the function body; just tweak the flags and proceed.

12690 top-level local variables.

12734 (clone_underlying type): Split out of pushdecl.
12735 (c_print_identifier): Update to match changes to struct
12737 (poplevel): Delete #if 0 block. Make externals invisible
12738 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
12739 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
12740 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12741 (duplicate-decls): For real parm decl after a forward decl,
12742 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
12743 foo(...) { } with only a warning. Say whether a previous

12746 local-over-local. Clarify comments.
12747 (pushdecl): Rewritten. There is no longer a distinction
12748 between global and local symbol values; they're all
12749 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
12750 DECL_EXTERNAL decls, and use any_external_decl to check
12751 against previous externals. Kill #if 0 blocks. Don't
12752 tolerate error_mark_node being NULL.
12753 (pushdecl_top_level): Handle only those cases which
12754 Objective C (the only user) needs.
12755 (pushdecl_function_level): New function.
