8802 (pushlevel): Ignore argument. Do not push another binding
8803 level on the transition from the parameters to the top level
8804 of the function body; just tweak the flags and proceed.

8854 (poplevel): Delete #if 0 block. Make externals invisible
8855 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
8856 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
8857 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
8858 (duplicate-decls): For real parm decl after a forward decl,
8859 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

8863 local-over-local. Clarify comments.
8864 (pushdecl): Rewritten. There is no longer a distinction
8865 between global and local symbol values; they're all
8866 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
8867 DECL_EXTERNAL decls, and use any_external_decl to check
8868 against previous externals. Kill #if 0 blocks. Don't
8869 tolerate error_mark_node being NULL.

8871 Objective C (the only user) needs.
8872 (pushdecl_function_level): New function.
8873 (implicitly_declare): Create ordinary decls with

8889 from build_external_ref.

8894 IDENTIFIER_GLOBAL_VALUE.
