4720 (pushlevel): Ignore argument. Do not push another binding
4721 level on the transition from the parameters to the top level
4722 of the function body; just tweak the flags and proceed.

4772 (poplevel): Delete #if 0 block. Make externals invisible
4773 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
4774 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
4775 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
4776 (duplicate-decls): For real parm decl after a forward decl,
4777 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

4781 local-over-local. Clarify comments.
4782 (pushdecl): Rewritten. There is no longer a distinction
4783 between global and local symbol values; they're all
4784 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
4785 DECL_EXTERNAL decls, and use any_external_decl to check
4786 against previous externals. Kill #if 0 blocks. Don't
4787 tolerate error_mark_node being NULL.

4789 Objective C (the only user) needs.
