13303 current_binding_level->tags if asked for thislevel_only or if
13304 we might have to diagnose "struct foo; union foo;"
13305 (pushlevel): Ignore argument. Do not push another binding
13306 level on the transition from the parameters to the top level
13307 of the function body; just tweak the flags and proceed.

13310 top-level local variables.

13355 (c_print_identifier): Update to match changes to struct
13357 (poplevel): Delete #if 0 block. Make externals invisible
13358 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
13359 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
13360 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
13361 (duplicate-decls): For real parm decl after a forward decl,
13362 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
13363 foo(...) { } with only a warning. Say whether a previous

13366 local-over-local. Clarify comments.
13367 (pushdecl): Rewritten. There is no longer a distinction
13368 between global and local symbol values; they're all
13369 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
13370 DECL_EXTERNAL decls, and use any_external_decl to check
13371 against previous externals. Kill #if 0 blocks. Don't
13372 tolerate error_mark_node being NULL.
13373 (pushdecl_top_level): Handle only those cases which
13374 Objective C (the only user) needs.
13375 (pushdecl_function_level): New function.
13376 (implicitly_declare): Create ordinary decls with
