10290 current_binding_level->tags if asked for thislevel_only or if
10291 we might have to diagnose "struct foo; union foo;"
10292 (pushlevel): Ignore argument. Do not push another binding
10293 level on the transition from the parameters to the top level
10294 of the function body; just tweak the flags and proceed.

10297 top-level local variables.

10341 (clone_underlying type): Split out of pushdecl.
10342 (c_print_identifier): Update to match changes to struct
10344 (poplevel): Delete #if 0 block. Make externals invisible
10345 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10346 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10347 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10348 (duplicate-decls): For real parm decl after a forward decl,
10349 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10350 foo(...) { } with only a warning. Say whether a previous

10352 (warn_if_shadowing): Now handles all shadowing, not just
10353 local-over-local. Clarify comments.
10354 (pushdecl): Rewritten. There is no longer a distinction
10355 between global and local symbol values; they're all
10356 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10357 DECL_EXTERNAL decls, and use any_external_decl to check
10358 against previous externals. Kill #if 0 blocks. Don't
10359 tolerate error_mark_node being NULL.
10360 (pushdecl_top_level): Handle only those cases which
10361 Objective C (the only user) needs.
10362 (pushdecl_function_level): New function.
10363 (implicitly_declare): Create ordinary decls with
10364 C_DECL_IMPLICIT set. Recycle old decls, however they got

10376 global_binding_level in extremis.
10378 * c-typeck.c (undeclared_variable): New static function, split
10379 from build_external_ref.
10380 (build_external_ref): Use DECL_CONTEXT, not
