216 we might have to diagnose "struct foo; union foo;"
217 (pushlevel): Ignore argument. Do not push another binding
218 level on the transition from the parameters to the top level
219 of the function body; just tweak the flags and proceed.
220 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
221 a function body, separate the parameter list from the
222 top-level local variables.
223 (set_block): Do nothing.

235 empty functions. Otherwise, don't call poplevel.

269 (poplevel): Delete #if 0 block. Make externals invisible
270 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
271 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
272 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
273 (duplicate-decls): For real parm decl after a forward decl,
274 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
275 foo(...) { } with only a warning. Say whether a previous
276 declaration was implicit.
277 (warn_if_shadowing): Now handles all shadowing, not just
278 local-over-local. Clarify comments.
279 (pushdecl): Rewritten. There is no longer a distinction
280 between global and local symbol values; they're all
281 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
282 DECL_EXTERNAL decls, and use any_external_decl to check
283 against previous externals. Kill #if 0 blocks. Don't
284 tolerate error_mark_node being NULL.

286 Objective C (the only user) needs.

298 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
299 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.

301 global_binding_level in extremis.
303 * c-typeck.c (undeclared_variable): New static function, split
304 from build_external_ref.
305 (build_external_ref): Use DECL_CONTEXT, not
306 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides

309 IDENTIFIER_GLOBAL_VALUE.
