9224 we might have to diagnose "struct foo; union foo;"
9225 (pushlevel): Ignore argument. Do not push another binding
9226 level on the transition from the parameters to the top level
9227 of the function body; just tweak the flags and proceed.

9277 (poplevel): Delete #if 0 block. Make externals invisible
9278 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9279 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9280 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9281 (duplicate-decls): For real parm decl after a forward decl,
9282 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

9286 local-over-local. Clarify comments.
9287 (pushdecl): Rewritten. There is no longer a distinction
9288 between global and local symbol values; they're all
9289 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9290 DECL_EXTERNAL decls, and use any_external_decl to check
9291 against previous externals. Kill #if 0 blocks. Don't
9292 tolerate error_mark_node being NULL.

9294 Objective C (the only user) needs.
9295 (pushdecl_function_level): New function.
9296 (implicitly_declare): Create ordinary decls with

9312 from build_external_ref.
