13337 current_binding_level->tags if asked for thislevel_only or if
13338 we might have to diagnose "struct foo; union foo;"
13339 (pushlevel): Ignore argument. Do not push another binding
13340 level on the transition from the parameters to the top level
13341 of the function body; just tweak the flags and proceed.

13344 top-level local variables.

13388 (clone_underlying type): Split out of pushdecl.
13389 (c_print_identifier): Update to match changes to struct
13391 (poplevel): Delete #if 0 block. Make externals invisible
13392 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
13393 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
13394 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
13395 (duplicate-decls): For real parm decl after a forward decl,
13396 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by

13400 local-over-local. Clarify comments.
13401 (pushdecl): Rewritten. There is no longer a distinction
13402 between global and local symbol values; they're all
13403 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
13404 DECL_EXTERNAL decls, and use any_external_decl to check
13405 against previous externals. Kill #if 0 blocks. Don't
13406 tolerate error_mark_node being NULL.
13407 (pushdecl_top_level): Handle only those cases which
13408 Objective C (the only user) needs.
13409 (pushdecl_function_level): New function.
13410 (implicitly_declare): Create ordinary decls with
13411 C_DECL_IMPLICIT set. Recycle old decls, however they got
