8342 (pushlevel): Ignore argument. Do not push another binding
8343 level on the transition from the parameters to the top level
8344 of the function body; just tweak the flags and proceed.

8394 (poplevel): Delete #if 0 block. Make externals invisible
8395 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
8396 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
8397 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
8398 (duplicate-decls): For real parm decl after a forward decl,
8399 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
8400 foo(...) { } with only a warning. Say whether a previous
8401 declaration was implicit.
8402 (warn_if_shadowing): Now handles all shadowing, not just
8403 local-over-local. Clarify comments.
8404 (pushdecl): Rewritten. There is no longer a distinction
8405 between global and local symbol values; they're all
8406 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
8407 DECL_EXTERNAL decls, and use any_external_decl to check
8408 against previous externals. Kill #if 0 blocks. Don't
8409 tolerate error_mark_node being NULL.

8411 Objective C (the only user) needs.
8412 (pushdecl_function_level): New function.
8413 (implicitly_declare): Create ordinary decls with

8429 from build_external_ref.

8434 IDENTIFIER_GLOBAL_VALUE.
