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

243 a function body, separate the parameter list from the

291 (poplevel): Delete #if 0 block. Make externals invisible
292 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
293 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
294 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
295 (duplicate-decls): For real parm decl after a forward decl,
296 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
297 foo(...) { } with only a warning. Say whether a previous
298 declaration was implicit.
299 (warn_if_shadowing): Now handles all shadowing, not just
300 local-over-local. Clarify comments.
301 (pushdecl): Rewritten. There is no longer a distinction
302 between global and local symbol values; they're all
303 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
304 DECL_EXTERNAL decls, and use any_external_decl to check
305 against previous externals. Kill #if 0 blocks. Don't
306 tolerate error_mark_node being NULL.

308 Objective C (the only user) needs.

323 global_binding_level in extremis.
325 * c-typeck.c (undeclared_variable): New static function, split
326 from build_external_ref.
327 (build_external_ref): Use DECL_CONTEXT, not
328 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides

331 IDENTIFIER_GLOBAL_VALUE.
