5569 (pushlevel): Ignore argument. Do not push another binding
5570 level on the transition from the parameters to the top level
5571 of the function body; just tweak the flags and proceed.

5621 (poplevel): Delete #if 0 block. Make externals invisible
5622 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
5623 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
5624 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
5625 (duplicate-decls): For real parm decl after a forward decl,
5626 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
5627 foo(...) { } with only a warning. Say whether a previous
5628 declaration was implicit.

5630 local-over-local. Clarify comments.
5631 (pushdecl): Rewritten. There is no longer a distinction
5632 between global and local symbol values; they're all
5633 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
5634 DECL_EXTERNAL decls, and use any_external_decl to check
5635 against previous externals. Kill #if 0 blocks. Don't
5636 tolerate error_mark_node being NULL.

5638 Objective C (the only user) needs.
5639 (pushdecl_function_level): New function.
5640 (implicitly_declare): Create ordinary decls with
