11154 (pushlevel): Ignore argument. Do not push another binding
11155 level on the transition from the parameters to the top level
11156 of the function body; just tweak the flags and proceed.

11204 (c_print_identifier): Update to match changes to struct
11206 (poplevel): Delete #if 0 block. Make externals invisible
11207 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
11208 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
11209 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
11210 (duplicate-decls): For real parm decl after a forward decl,
11211 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

11215 local-over-local. Clarify comments.
11216 (pushdecl): Rewritten. There is no longer a distinction
11217 between global and local symbol values; they're all
11218 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
11219 DECL_EXTERNAL decls, and use any_external_decl to check
11220 against previous externals. Kill #if 0 blocks. Don't
11221 tolerate error_mark_node being NULL.

11223 Objective C (the only user) needs.
11224 (pushdecl_function_level): New function.
