8459 (pushlevel): Ignore argument. Do not push another binding
8460 level on the transition from the parameters to the top level
8461 of the function body; just tweak the flags and proceed.

8511 (poplevel): Delete #if 0 block. Make externals invisible
8512 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
8513 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
8514 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
8515 (duplicate-decls): For real parm decl after a forward decl,
8516 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

8520 local-over-local. Clarify comments.
8521 (pushdecl): Rewritten. There is no longer a distinction
8522 between global and local symbol values; they're all
8523 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
8524 DECL_EXTERNAL decls, and use any_external_decl to check
8525 against previous externals. Kill #if 0 blocks. Don't
8526 tolerate error_mark_node being NULL.

8528 Objective C (the only user) needs.
8529 (pushdecl_function_level): New function.
8530 (implicitly_declare): Create ordinary decls with
8531 C_DECL_IMPLICIT set. Recycle old decls, however they got

8543 global_binding_level in extremis.
