1780 we might have to diagnose "struct foo; union foo;"
1781 (pushlevel): Ignore argument. Do not push another binding
1782 level on the transition from the parameters to the top level
1783 of the function body; just tweak the flags and proceed.

1799 empty functions. Otherwise, don't call poplevel.

1831 (c_print_identifier): Update to match changes to struct
1833 (poplevel): Delete #if 0 block. Make externals invisible
1834 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1835 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1836 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1837 (duplicate-decls): For real parm decl after a forward decl,
1838 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1839 foo(...) { } with only a warning. Say whether a previous
1840 declaration was implicit.

1842 local-over-local. Clarify comments.
1843 (pushdecl): Rewritten. There is no longer a distinction
1844 between global and local symbol values; they're all
1845 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1846 DECL_EXTERNAL decls, and use any_external_decl to check
1847 against previous externals. Kill #if 0 blocks. Don't
1848 tolerate error_mark_node being NULL.

1850 Objective C (the only user) needs.
1851 (pushdecl_function_level): New function.
1852 (implicitly_declare): Create ordinary decls with
1853 C_DECL_IMPLICIT set. Recycle old decls, however they got
1855 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0

1865 global_binding_level in extremis.
1867 * c-typeck.c (undeclared_variable): New static function, split
1868 from build_external_ref.
