11158 we might have to diagnose "struct foo; union foo;"
11159 (pushlevel): Ignore argument. Do not push another binding
11160 level on the transition from the parameters to the top level
11161 of the function body; just tweak the flags and proceed.

11209 (c_print_identifier): Update to match changes to struct
11211 (poplevel): Delete #if 0 block. Make externals invisible
11212 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
11213 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
11214 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
11215 (duplicate-decls): For real parm decl after a forward decl,
11216 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

11220 local-over-local. Clarify comments.
11221 (pushdecl): Rewritten. There is no longer a distinction
11222 between global and local symbol values; they're all
11223 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
11224 DECL_EXTERNAL decls, and use any_external_decl to check
11225 against previous externals. Kill #if 0 blocks. Don't
11226 tolerate error_mark_node being NULL.

11228 Objective C (the only user) needs.
11229 (pushdecl_function_level): New function.
