9191 (pushlevel): Ignore argument. Do not push another binding
9192 level on the transition from the parameters to the top level
9193 of the function body; just tweak the flags and proceed.

9243 (poplevel): Delete #if 0 block. Make externals invisible
9244 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9245 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9246 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9247 (duplicate-decls): For real parm decl after a forward decl,
9248 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

9252 local-over-local. Clarify comments.
9253 (pushdecl): Rewritten. There is no longer a distinction
9254 between global and local symbol values; they're all
9255 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9256 DECL_EXTERNAL decls, and use any_external_decl to check
9257 against previous externals. Kill #if 0 blocks. Don't
9258 tolerate error_mark_node being NULL.

9260 Objective C (the only user) needs.
9261 (pushdecl_function_level): New function.
9262 (implicitly_declare): Create ordinary decls with

9278 from build_external_ref.

9283 IDENTIFIER_GLOBAL_VALUE.
