1764 (pushlevel): Ignore argument. Do not push another binding
1765 level on the transition from the parameters to the top level
1766 of the function body; just tweak the flags and proceed.

1816 (poplevel): Delete #if 0 block. Make externals invisible
1817 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1818 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1819 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1820 (duplicate-decls): For real parm decl after a forward decl,
1821 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1822 foo(...) { } with only a warning. Say whether a previous
1823 declaration was implicit.

1825 local-over-local. Clarify comments.
1826 (pushdecl): Rewritten. There is no longer a distinction
1827 between global and local symbol values; they're all
1828 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1829 DECL_EXTERNAL decls, and use any_external_decl to check
1830 against previous externals. Kill #if 0 blocks. Don't
1831 tolerate error_mark_node being NULL.

1833 Objective C (the only user) needs.
1834 (pushdecl_function_level): New function.
1835 (implicitly_declare): Create ordinary decls with

1848 global_binding_level in extremis.

1851 from build_external_ref.
