12782 (pushlevel): Ignore argument. Do not push another binding
12783 level on the transition from the parameters to the top level
12784 of the function body; just tweak the flags and proceed.

12832 (c_print_identifier): Update to match changes to struct
12834 (poplevel): Delete #if 0 block. Make externals invisible
12835 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
12836 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
12837 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12838 (duplicate-decls): For real parm decl after a forward decl,
12839 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

12843 local-over-local. Clarify comments.

12845 between global and local symbol values; they're all
12846 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
12847 DECL_EXTERNAL decls, and use any_external_decl to check
12848 against previous externals. Kill #if 0 blocks. Don't
12849 tolerate error_mark_node being NULL.

12851 Objective C (the only user) needs.
12852 (pushdecl_function_level): New function.
