1795 we might have to diagnose "struct foo; union foo;"
1796 (pushlevel): Ignore argument. Do not push another binding
1797 level on the transition from the parameters to the top level
1798 of the function body; just tweak the flags and proceed.

1846 (c_print_identifier): Update to match changes to struct
1848 (poplevel): Delete #if 0 block. Make externals invisible
1849 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1850 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1851 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1852 (duplicate-decls): For real parm decl after a forward decl,
1853 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1854 foo(...) { } with only a warning. Say whether a previous
1855 declaration was implicit.
1856 (warn_if_shadowing): Now handles all shadowing, not just
1857 local-over-local. Clarify comments.
1858 (pushdecl): Rewritten. There is no longer a distinction
1859 between global and local symbol values; they're all
1860 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1861 DECL_EXTERNAL decls, and use any_external_decl to check
1862 against previous externals. Kill #if 0 blocks. Don't
1863 tolerate error_mark_node being NULL.

1865 Objective C (the only user) needs.
1866 (pushdecl_function_level): New function.
1867 (implicitly_declare): Create ordinary decls with
1868 C_DECL_IMPLICIT set. Recycle old decls, however they got
1870 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
1871 for C_DECL_INVISIBLE symbols.
1872 (lookup_name_current_level): Likewise. Use chain_member.
