12880 (pushlevel): Ignore argument. Do not push another binding
12881 level on the transition from the parameters to the top level
12882 of the function body; just tweak the flags and proceed.

12930 (c_print_identifier): Update to match changes to struct
12932 (poplevel): Delete #if 0 block. Make externals invisible
12933 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't

12935 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
12936 (duplicate-decls): For real parm decl after a forward decl,
12937 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

12941 local-over-local. Clarify comments.
12942 (pushdecl): Rewritten. There is no longer a distinction
12943 between global and local symbol values; they're all
12944 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
12945 DECL_EXTERNAL decls, and use any_external_decl to check
12946 against previous externals. Kill #if 0 blocks. Don't
12947 tolerate error_mark_node being NULL.

12949 Objective C (the only user) needs.
12950 (pushdecl_function_level): New function.
12951 (implicitly_declare): Create ordinary decls with
