11163 we might have to diagnose "struct foo; union foo;"
11164 (pushlevel): Ignore argument. Do not push another binding
11165 level on the transition from the parameters to the top level
11166 of the function body; just tweak the flags and proceed.

11169 top-level local variables.

11213 (clone_underlying type): Split out of pushdecl.
11214 (c_print_identifier): Update to match changes to struct
11216 (poplevel): Delete #if 0 block. Make externals invisible
11217 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
11218 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
11219 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
11220 (duplicate-decls): For real parm decl after a forward decl,
11221 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

11225 local-over-local. Clarify comments.
11226 (pushdecl): Rewritten. There is no longer a distinction
11227 between global and local symbol values; they're all
11228 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
11229 DECL_EXTERNAL decls, and use any_external_decl to check
11230 against previous externals. Kill #if 0 blocks. Don't
11231 tolerate error_mark_node being NULL.
11232 (pushdecl_top_level): Handle only those cases which
11233 Objective C (the only user) needs.
11234 (pushdecl_function_level): New function.
11235 (implicitly_declare): Create ordinary decls with
11236 C_DECL_IMPLICIT set. Recycle old decls, however they got

11251 from build_external_ref.
